Integration in time domain causes high frequency noise signals. If possible use a displacement transducer to measure the displacement instead of double integrating the acceleration data. If this is not possible, then try to use some digital filters during integration. However if you conduct the...
I guess the wheatstone bridge is a quarter bridge. If the duration of time of the test is long or the tempereture varience is high, there may be an offset in the strain readings of the gage. If you could measure the test with a poisson half bridge you will have the chance to compensate for the...
www.vishay.com is a useful site. You can find both information about instrumentation and how to apply strain gages. For the case you need to purchase an application kit containing the necessary surface preparation and bonding accessories. I think you are going to apply quarter bridge so for the...
Excite the system with an impulse hammer and get the results. From the transfer functions you can plot the mode shapes and operational deflection shapes(ODS). If you can excite the system with a bandwidth of more than 2 kHz, The Operational deflection shapes directly show how the system moves at...
