To measure the vibration I am just using a Extech Vibration meter which does not give me any frequency information. I haven't been able to talk my company into buying a DAQ or similar frequency analyzer. Are there any 2+ channel frequency vibration analyzers you know of you would recommend for...

I haven't done an R&R Study we are a small company and I sometimes overlook those things. I will have some people set up and run the tests again on some more machines. I have currently ran the test on just three different machines with similar results. I have balanced the shaft a couple of...

The Vibration increases in both displacement and velocity when measuring it with an accelerometer in both horizontal and vertical directions. At 500 rpm's is where the displacement vibration is the worst with both shafts with the harder one vibrating more, but they run from 90 rpm's to 2000...

Hi, I recently had a problem with our machines shafts where the vibration increases after heat treating our shafts. The initial test was done with a 1040 steel shaft that was not heat treated for the first prototype and had a hardened chrome plating. The production sample Shaft was done with a...
