In theory based on a single degree of freedom system, it is calculated to be as such. If you are calculating with ANSYS, do not use the full but instead use a reduced degrees of freedom you're interested in.
The moment you included the mass and shape factor in the analytical model, you have...
hi,
I have design such a fixture way back but we call it mechanical signal amplifier. The main reason is to increase the signal that the DUT is experiencing. The material for the fixture and the way to control the gain take more work in the analysis side. Good knowledge of damping coefficient...
Fixture can be made for different testing configurations. What I normally do is create a fixture for multiple parts on test provided that the parts function will not interfere with each other. The shaker table has bolt pattern that you can easily adapt to. Ensure that the pattern is...
"I can extract Natural Frequencies using FEA software. For simple shock tests (such as 40g over 10 ms)could I not make use of this frequency info"
Why not? This is done on a transient analysis and you have to create the profile of the signal and apply it to your model.
