Simple method for model selection of vibration table in simulation transportation
Simple method for model selection of vibration table in simulation transportation
Step 1: Understand the test requirements for the product to be tested:
External size, weight (mass), test frequency range, maximum acceleration, maximum displacement (double peak), required vibration direction, whether the test can stand on its head in any direction, etc.
Step 2: Based on the sample size and frequency range, make a preliminary estimate of the selected analog transport shaking table model
The third step: check whether the thrust can meet the requirements,
The formula F = ma is used, where m includes the quality of the sample, the quality of the expansion platform, the quality of the moving parts of the platform body (check the parameters of various vibration models), and the quality of the fixture.
Step 4: The conditions for correct selection of vibration table in simulated transportation are as follows: the maximum thrust of the selected model must be greater than the checking result F, and the unit used should be the same (N or Kgf).
Step 5: Approve whether the frequency upper limit of the analog transport shaking table extension table is greater than required.
Step 6: Check that the maximum amplitude of the system is greater than required.
