LogicData G.m.b.H. – DEWE-43A

Introduction

LOGICDATA is constantly in motion when it comes to innovation and new developments. We continuously strive to create the unexpected.

LOGICDATA develops mechatronic system solutions for adjustable home and office furniture. We constantly strive to create new and better technology.

As we are implementing industry-leading solutions in to our products, we have to rely a lot on our internal testing, as we have to create our own database for evaluating solutions. For example, at the end, when we are testing final design of the actuator that we would like to release and start to sell, we are performing more than 200 tests that this actuator design needs to pass in order for us to be OK.

This means, that we need to have a possibility to perform a wide variety of tests quickly and easy on different locations. We realized, that DEWE-43A offers exactly this. With TEDS support and setup storing, we are able to quickly build up our test setup on the spot where it is needed and perform our tests.

In this note, I will present different measuring scenarios, where flexibility of DEWE-43A is helping us in our daily work.

Motor Performance Test

To be able to move furniture, we need to have a motor. Therefore, we build a simple test device with motor holder, torque and speed sensor and brake. Equipment used:

• DEWE-43A
• DEWESoft X2
• DSI-V-200
• LEM LTSR 15-NP Current Sensor x4
• 1535 Peaktech Power Supply 600W
• RRFL-I-1-n ETH 1Nm Torque sensor
• HB-140M-2 Magtrol Hysteresis brake
• Self-made brake controller

We are using PMSM 3 phase motor with our own controller. We are monitoring current flow in each phase, DC supply current and voltage and are able to calculate energy provided to the motor. On the mechanical side, we are measuring torque and speed and are therefore able to calculate mechanical energy going from the motor. Our test runs through different loads and speeds and we collect all the data. Using great mathematical functions included in DEWESoft X2, we are able to calculate efficiency of the motor and generate motor performance curve live while doing a measurement.

Performance during Simulation of Lifetime

It is also important to us to know, how the performance of our actuator may change over lifetime. Therefore, we are doing different performance related measurements during a life test of the actuator. For this, a portable measuring solution is very important, as we have to move from actuator to actuator and perform the tests. Equipment used:

• DEWE-43A
• DEWESoft X2
• DSI-V-200
• LEM LTSR 15-NP Current Sensor
• Self-made digital counter
• HBM U10M 2,5kN Force sensor

While actuator is loaded with defined load over the lifetime, we connect our equipment and measure DC voltage and current going in to the actuator. With self-made digital counter cable, we tap in to the communication between control box and actuator and get voltage peak every time the motor rotates. With it, we can use counter setup in Dewesoft, to instantly calculate motor speed. With the force sensor mounted under the actuator, we know the load actuator needs to move and we can calculate mechanical energy going out of the actuator. With this information, we can calculate actuator efficiency. At the end of the life test, we can compare results from the same actuator over its lifetime and note any changes.

Table acceleration and deceleration profile

Acceleration and deceleration profile of the table plays a very important role in a user experience and overall perception of the quality of the table. Therefore, different systems has been objectively and subjectively evaluated in order to find the best one and create a guideline for our future products. Equipment used:

• DEWE-43A
• DEWESoft X2
• Variohm RF603 Laser distance sensor

Laser was mounted on a special profile and was measuring distance to the table top. Table was moved up and down and position recorded. From this position, acceleration and deceleration profile was extracted and compared to subjective evaluations.

Conclusion

As visible from the presented examples, portability and variability are essential for our measurements. What’s more, prefect implementation of advanced mathematical formulas, calculated in real time, give our engineers possibility to have live view of calculated results and can adjust measured samples during testing. This increases efficiency of testing and give us desired results straight out of first measurement.

Tractor Pulling Sport

Introduction

At which sport do you see the combination of C10H20…C15H28 (or CH3OH)+ 1000…8000 bhp + >100 dB on a short track of 100 meters? You are at a tractor pulling event where standard and modified tractors (running on diesel fuel or methanol) compete with each other in strength and over distance.

The sport originates in the 50’s from the United States, where farmers battled with each other by pulling a weight over a certain distance. In 1977 the sport was introduced in Europe (The Netherlands) and is still growing in popularity all over Europe.

The rules are simple: pull a 28000 kg sled over a 100 m track. However the tricky part is, that the sled will dig itself, due to its weight, more and more into the soil as the distance progresses. This causes a higher and higher friction: thus more resistance to the tractor.

Measurement History

There are several classes in the Tractor Pulling Sport, from Light weight to Heavy Modified. All these Specials are unique and have an individual design based on an engine that could for instance be a tank engine or even a combination of multiple helicopter turbines. In the early years nothing was measured. Over the last 10 years data loggers (5 to 10 pt/sec) were used for measurement, but this is not enough anymore.

Signals and Sensors

Typical ‘standard’ configuration needed:

• 6 to 10 Pressure sensors (turbo(s), inlet, oil, water, gasoline)
• 6 to 16 Temperatures (one sensor per cylinder exhaust, oil)
• 2 to 6 Counters (wheel speeds, engine rpm, turbo rpm)
• Video (now post sync GoPro video)
• Math channels

Expected future requests:

• GPS (at least 5 pt/sec as the run is only 10 seconds!!)
• Combustion pressure (only for expert users)
• Vibration measurement
• Order tracking
• Alarms (indicator and output)
• Video camera that can withstand the huge shocks/vibrations

Measurement & Analyse

First tests were done with the Dewesoft MINITAURs system and a CAN-bus measuring unit for temperatures.

Conclusion

By collecting data over a time span of just 1 minute (the race takes only 10 seconds) the high-speed data provides at lot of useful information to optimize the engine. Next to that, engine failures can already be detected in an early stage, which saves money and down time of the machine. The Dewesoft solution is compact, fast and has an easy to use configurable user interface. For the driver a simple interface can be configured with just some key information. After the run the experts can perform extensive offline analyses and create statistics.

A lot can go wrong at tractor pulling event, therefore analyzing of the data really helps them to prevent accidents like this.

Dynamic Tests on Industrial Shelter

Introduction

This presentation describes the test campaign carried out, by personnel of Rina Consulting S.p.A, on an industrial shelter for telecommunications. The scope of this was to check, evaluate and improve the capacity of the shelter to dampen the vibrations that affect the antenna during transportation by truck along urban and not urban roads. This shelter can be used to ensure emergency communications during natural catastrophes (earth quakes, avalanches ..etc ). For this reason, it must have the ability to avoid damages to antenna and other systems during transportation, especially on rough roads. Tests were performed using Dewesoft Sirius 8acc and X2 software to show in real time raw data and data analysis to our client.

Two test campaigns were performed for a total of 11 measuring runs for a total of 120 km covered. At each run the constraints and the damping characteristics were changed to find best configuration able to minimize amplifications of the antenna’s vibrations. Three measuring points, two tri-axial and one bi-axial, were implemented using IEEPE accelerometers and an action cam connected by USB to the laptop.

Test Campaigns

The tested tele-communications system was designed to work stand-alone both in urban and not urban contexts. It’s made up of a shelter, containing electronics devices, generators and him fuel tanks, of a system of four self-leveling legs, which permit to install it onto irregular terrains and of an extensible arm with a rotation pin on the top. The rotation pin supports a rotating antenna.

Three measuring points were installed:

• One on the “iso-corner”, to measure input accelerations to the structures. Tri-axial. Point A
• One on the pin of arm, at the base of antenna. Bi-axial (Y and Z directions). Point B
• One on the antenna, to measure accelerations response. Tri-axial. Point C

Rina Consulting S.p.A. carried on all activities involved in this work:

• choice of measuring points, in accordance with client indications and necessities
• sensor chain installation
• setting of Dewesoft X2 measuring software
• data acquisition and post analysis

Combinations of constraints and dampers

Tests were performed during transportation of the system with a truck for a total of 11 measuring runs. For each run, the types of constraints and damper elements were changed by client personnel. This was done to find the combination that permits to minimize movements and vibrations of the antenna.

First campaign:

1. Elastic hooks at the level of the antenna rotation pin. Radome free
2. Rotation pin and radome free
3. Rotation pin blocked. Radome free

Second campaign:

1. Rotation pin free and radome on damping mat
2. Rotation pin resting on 6 dampers and radome on rigid supports
3. Rotation pin resting on 6 dampers and radome free
4. Rotation pin resting on 4 dampers and radome on dampened supports
5. Rotation pin fixed on 4 dampers and radome on dampened support
6. Not communicated by client
7. Not communicated by client
8. Not communicated by client

Measuring Chain

Sensors and camera were fixed on measuring points by epoxy glue and by mechanical solutions. Height coaxial cable RG58 were installed from the sensors to the Sirius 8Acc, located on drive cabin. Accelerometers used were PCB 393A03 (IEEPE, 1 V/g sensitivity). Sampling rate was 1200 Hz, to assure a band of 500 Hz for data signals. Camera signals were achieved directly in Dewesoft X2, as signal sensors.

Data Analysis

As mentioned before, the main scope of this work is to quantify magnifications of antenna’s and arm’s vibrations comparing to the vibrations in going to the shelter, in iso-corner point. To perform this, sub request of client, a simple calculation of transfer function H(s) was performed on accelerometers time data.

For each measuring direction the X,Y and Z the signals of accelerometers were used to calculate H functions as HXA,B HXA,C HYA,B --- HZA,C . Or, in other words, three matrices were been built, one for each measuring direction:

The H function was calculated using math instruments present in Dewesoft X2. This part of data elaboration was executed after the completions of a single run of measure.

Results

For each measuring run a set of H(s) functions was calculated for B and C points (rotation pin and antenna positions respectively) for X, Y, and Z direction:

After, to evaluate the performances of different dumping solutions , for each measuring point and for each direction, all the H(s) functions were gathered together in a Excel’s sheets&graph in terms of magnitude:

Conclusion

The solutions tested show various behaviours along the frequency range. No solutions tested it’s efficient on the entire spectrum. Many solutions are efficient at low frequencies but not around the value of 40 Hz (characteristic of truck’s rotating wheels). Other solutions magnify the response at very low frequencies but are more efficient in the rest of the spectrum. Anyway the results obtained during the test allowed the customer to make a choice. This has fallen on those that minimize magnification at very low frequencies (eg red, Test # 6 and #7)

DEWESoft X3 SP3

The Dewesoft team is pleased to announce the release of the new DEWESoft X3 SP3.

The new version of DEWESoft X includes a great mix of stability and performance improvements on the already existing functionality, as well as an array of brand new features which enhance the user experience and make Dewesoft an even easier tool to use.

Listed below are some of the major changes as well as the minor, convenience features.

THE “DS-GRID” IS NOW AVAILABLE IN MATH

One of the most important features of DEWESoft X3 SP3 is that users now get access to the “DS-GRID” in the standard Math module. Following the unification theme of X3, the Math module was one of the last final core tools that was still using the older Delphi grid. SP3 not only adds the “DS-GRID” to math but also to other complex math modules like Balancing, Combustion/Power grid analysis,... With the grid, you of course also get access to new columns, which you customize to your liking.

NEW VISUAL CONTROL: 2D/3D TABLE

While 2D and 3D graph provide an interactive graphics visualization of your data, the new 2D / 3D table offers an easy access to numeric values of multidimensional data at any given point in time. You can display either matrices or multiple vectors (as long as they share the same axis), copy values to the clipboard, automatically color cells with out-of-bound values, ... all while conveniently sliding back and forth in time through your measurement.

Improved NET interface (cross trigger, RDP)

The NET interface is now greatly improved with the implementation of cross triggers that allow the triggers from any measurement unit to be used on any other unit. A big improvement is also the adition of the Windows Remote Desktop Protocol (RDP) as an option to remotely connect to slave measurement units which is even faster and more reliable than VNC.

Offline Krypton setup

Offline Krypton setup in now available in addition to SIRIUS and DEWE-43, which allows the simulation of Krypton measurement instruments to build setups without having the need for actual hardware.

LORD Microstrain wireless sensors supported

LORD Microstrain plugin was developed, allowing LORD Microstrain wireless sensors to be used with Dewesoft directly, without any additional interfaces or adapters.

OPC-UA Server / Client

The newely developed OPC UA Server and Client plugins allow Dewesoft to send and receive data from other OPC UA devices and therefore greatly improving the range and possibilities of integration with other devices and systems.
