Analysis Results - what does it mean?

Analysis Results - what does it mean?

Analysis Results - what does it mean?

I am new to the field of vibration testing and this may or may not be a trivial question. Please be gentle.

I've recently carried out some vibration tests on an optical table. The results from the accelerometer are given in m/s/s at a known frequency. How can I convert this to a displacement so I can get a handle on the magnitudes involved?

RE: Analysis Results - what does it mean?

I've talked with an associate about this and he offered the following:

You have a known frequency (Hz) which must be converted to radians/second (multiply frequency by 2*pi).  Next, divide your acceleration by your new constant (rad/sec) to get the velocity.  Divide again and you get displacement.

Alternatively, you could get ahold of an analysis package like Matlab and have it do the conversion.  I've used Matlab before, but not much with the signal analysis toolbox.

Good luck,

Cheers, thats exactly what I was looking for. I shall go away now and carry on with the testing.

White Paper – Your Construction ERP RFP Checklist
Selecting business software for a medium to enterprise-sized construction concern is extremely challenging in large part because most enterprise resource planning (ERP) suites originated in the world of repetitive manufacturing and are therefore a poor fit for a project and asset-centric business. However, midsize to large contractors need the predictable, auditable processes that ERP delivers. Download Now
