The range of industrial applications is so wide that they can be hardly covered in only few sentences. With the use of all possible inputs, extensive math, trigger functions and DCOM capabilities, the customers are using DEWESoft in lots of different ways. Here are only few basic application.

Development testing

When it comes to development, the new products must be checked in terms of performance, long term stability, electrical testing, noise and vibration and other. DEWESoft is one of the very rare software packages which can do everything at once. Imagine for example an electromotor. It must be checked for mechanical performance (RPM, torque), electrical performance with all analysis (voltage, current, power, efficiency, electrical troubles), for operational parameters like temperatures over longer time as well as sound and vibration picture, usually related to load and speed. DEWESoft is flexible enough to perform all these measurements at once, if needed. It's all a matter of setting up the system.

Example of industrial development application.

DEWESoft can record many different sources all fully synchronized, which can play crucial role in successful product development.

Stairways testing	Brake test system for stairways at Schindler Schindler, Austria	View
Application To get public approval, stairways need to pass several electrical as well as mechanical tests. For the development purposes, system must be capable of measuring together all parameters as well as high speed video. Measurement challenge All electrical parameters (power, harmonics, ...) are calculated from voltage and current and correlated to the mechanical parameters like displacement, rotation and speed. However it was also necessary to use high speed video (150 fps) and the advanced triggering capability of Dewesoft to be able to perform the measurement.

Electromotors testing	Testing of electro motors and making reports Koncar Institute, Croatia	View
Application Electro motors require test of electrical and mechanical parameters. They were using dedicated power instruments and dedicated device for testing mechanical parameters, but then they had to manually correlate measurement and hand write the result for each measurement point. Additionally they were searching for the system to be able to do special application like super zoom FFT to determine the faults on the rotor. Measurement challenge The system is able to record voltage and current and calculate very accurately all the power parameters of the motor. Additionally it is able to measure mechanical parameters like speed, torque, vibrations and temperatures in a single box, which is a big benefit. When the measurements are finished, the data is exported in special script in Flexpro to create printed reports in a matter of seconds after the tests. Test setup Test setup

Production testing

Of course all these measurements can be used also for production tests. Automated reports can be generated from DEWESoft with the use of post processing packages like Flexpro of Excel. The usage of DCOM provides means of automated operation as well as different ways of storage - for example to the database.

Quality control for molding	Quality control for molding TokaiRika, Japan	View
Application For molding applications it is very important to ensure correct temperature and pressure parameters at the time of production. Therefore the need is to have IR camera as well as analog parameters to checl the quality of molding. Measurement challenge The measurement challenge is to record analog data of temperature and pressure, counter channels for linear encoders and a thermovision camera for non-contact measurement of temperatures. All the parameters have to be synchronized. All the parameters are showing if the mold is evenly heating up and therefore ensuring the good quality of production. DEWESoft in action - data recording

Structural testing

When designing the vehicle, all mechanical parts are done with the use of computer and qualified with finite element method to determine natural frequencies of the structures. However, the need to check those method is needed more than ever to produce a closed loop to correct the models that they fit the measurement results. DEWESoft provides DeweFRF add-on software to add the ability to import the geometry models, measure transfer functions with the use of either hammer or shaker excitation and see fascinating animation of the structures on the fly. Data can be easily exported to UFF format for further processing.

Order tracking

When determining how the structures behave under real operating conditions, order tracking provides the means of seeing the structural response to real life excitation. The rotating parts of the vehicle like engine, shafts or the wheels creates excitation forces on the structure. Did you ever had a car starting to rattle and shake at certain vehicle speed? This car was for sure not tested with DEWESoft and those high vibrations were result resonance frequencies of some elements at certain input frequencies.

By measuring rotating speed and the response (in terms of vibration, noise and others) the Nyquist, Bode and three dimensional FFTs are generated on the fly giving clear picture of the frequencies having a problem.

Torsional vibration

If the acceleration sensors provides information about linear movement, torsional vibration procedure provides the information about angular vibration. Imagine a long shaft going through the vehicle. Like each structure has linear natural frequencies, this shaft will have angular natural frequencies resulting at high angular vibration at certain rotation speed. To check the bending of the shaft, we mount any kind of angular sensor on each end of the shaft and measure the angle difference. The data can be used in order tracking to give a clear indication of natural frequencies.

Determine the twist angle of a shaft, crank shaft or other rotational mechanic parts of an engine.

Power analysis

DEWESoft has a very nice power module providing power (voltage, current, active, reactive, total power) and power quality (harmonics, flicker) parameters adding the value to the measurements in industry. The products can be checked for power efficiency as well as how they are affected by the fluctuation of the grid and how they are affecting the power grid.

These quality of these measurements are the same as if you would buy a dedicated power instrument, but the greatest advantage is that DEWESoft is opened also to acquire other data giving a total solution for all the needed tests.

Distributed data acquisition

The distributed data acquisition in industry gives a very nice opportunity to the users to create a stack of high speed data acquisition devices. When we are talking about measurement of thousands of channels, there are more dedicated solutions which are cheaper than using DEWESoft.

But all those solution have a major disadvantage - they are limited in functions and acquisition rates. When we want to measure high speed data like voltage and current or vibrations, we need higher data rates as well as lots of online processing to reduce amount of data to some key parameters. In terms of critical events, data can be acquired with the high speed to capture a transient event.

High speed data capture

When it comes to high speed applications, DEWESoft can be used to capture high speed data and high speed video at the same time. Data can be acquired with up to 80 MB/second in stream mode (limited only by amount of hard disk space) or using on board memory capabilities acquiring data with hundreds of million samples per seconds.

As we all know, picture tells more than hundred words (or data points in our case) and therefore DEWESoft offers the acquisition of high speed video data. Video signals up to 100 frames per second can be streamed to the hard disk, but we can also use high speed video cameras with more than 100000 frames per seconds (but the amount of time is limited by the memory of the camera).

This fuse switch test includes a data recording from very high speed camera to capture exact switching moment. All data is synchronized.
