Data Translation: Vibration Measurement and Embedded ARM

The DT7837 combines 4-channel high accuracy dynamic signal data acquisition for noise, vibration, and acoustic applications with an embedded Cortex-A8 ARM processor. Four, 24-bit, IEPE (ICP®) sensor input data can be algorithmically processed in real time with the optional use of a 24-bit stimulus D/A generator and the results presented to a host for analysis.

Based on an Open-source Linux computing platform derived from the BeagleBone Black, you can build highly sophisticated applications using USB and Ethernet for host and client communication, microSD or serial UART interfaces. Complete source code is provided that can be modified and used without any restrictions. Further examples show how to develop an embedded application for any specific purpose using various open-source libraries and utilities.

The DT7837 software can be downloaded from the DT website. This file is a self-extracting compressed archive that will install the source code for the DT7837 kernel device drivers, device tree, and examples under the target directory on your Linux host computer when executed.

Data Physics: Understanding VI Curves and Their Significance

As each shaker is manufactured, Data Physics gathers Voltage vs. Current (VI) curves for that particular model.

The VI curves show the voltage and current output from the amplifier to the AC coil, typically recorded at full force bare table. The original VI curves can later be referred to and compared against current measurements as another health check of the shaker and amplifier assembly.

Figure 1 is a recently recorded VI curve for the LE-308/DSA10-20K shaker and amplifier system. You can see the Voltage starts at approximately 100V, which is right at the displacement limit of the shaker.

The voltage then gradually increases to approximately 105V, which is the velocity limit of 71 inches per second (1.8 m/s). Since Velocity is directly proportional to Voltage, this constant is maintained until you reach the Velocity to Force crossover frequency, which is approximately 80 Hz, at which point the Voltage drops and Current reaches its maximum.

You can see that the Current stays generally constant at approximately 125 Amperes through the entire frequency range of approximately 80-900 Hz, at which time the required current rolls off due to the “free energy” of the system dynamics.
Since we have tested this system at maximum force, the maximum current requirement should not change with payload except at the velocity crossover point. In other words, if you were to load a 150 lbs (68 kg) payload or a 250 lbs (113 kg) payload and operate the shaker to its full force output, the required current should remain a constant 125 Amperes.
The only exception to this rule would be at the Velocity to Acceleration cross over point which will shift down significantly due to the payload. However, the curve should look just the same as Figure 1; the only difference would be the point at which the Voltage and Current cross each other.

Courses ‘Introduction to Vibration’ and ‘Fixtures, Software and Specification’

 

In Autumn 2015 we will organise again the famous two-days course ‘Introduction to Vibration’ and it will take place in Breda (NL). This course aims to give more insight knowledge to the attendees in:
- testing with a shaker system
- dealing with several kind of tests
- reading the theoretical test and the implementation of the test
- designing a fixture

Here you can find the contents of this course.

A second course ‘Fixtures, Software and Specifications’ will be organised on the third day for those who are interested in aspects of vibration technology which lays beyond the introduction course. This day is intended to be an interactive course, where you can discuss problems related to vibration technology with the host(s) and your co-participants. You can even bring your own fixture(s), if you have questions about it and want to discuss it.




If you or one or more of your colleagues are interested in one or both courses, please inform us by clicking on the Mail button below.
