Problems with electric vibration testing
Thread Content
Question 1: I can operate the device without any issues when running sine waves. However, when running random waves, despite having all the parameters set correctly and constraints in place, as well as reasonable graph displays, channel 1 becomes active after just over 20 seconds of operation. What’s the problem? Question 2: For a vibration test lasting 90–100 minutes, with the frequency varying from 10 Hz to 55 Hz and then back to 10 Hz at a rate of 1 Hz/min, and an amplitude of 0.8 mm, how should the test profile be set up? The format of my home vibration tester is as follows: frequency, acceleration, left slope, right slope, upper alarm limit, lower alarm limit, upper interrupt limit, lower interrupt limit
Does anyone know? I tried it yesterday during the transport test: when the maximum frequency was set to 250, Channel 1 became active, while when the maximum frequency was set to 73, Channel 1 did not become active. However, the highest frequency in the target spectrum during the transport test is 200, so there shouldn’t be any problem with setting it to 250
Did I send it to the wrong place? Which section should it be posted in?
