Hi,
I have a 26' box truck from Hinos (Chinese diesel truck). I placed a couple accelerometers on the box to see what frequencies are present. Several low frequencies crop up (1.5, 3.7, 14.7, 35.0 Hz). To calculate the dominant frequency of the diesel engine it would be:
RPM/60 = Hz
Then the...
Hi All,
I am mounting a rectangular structure(115 lb)on the underbody of a commercial truck and need to isolate the vibrations being transferred from the truck while driving; The truck produces a low random vibration (1-15 Hz). I have been exploring options such as visco-elastic rubbers, and...
I am working on a research project that involves mounting a 5x6x0.375x120" beam to the side of a 18-wheeler. I have done a modal analysis to get an idea of the natural frequencies, I am looking into using MSC Adams in the future. Until then, I was planing on doing a stationary free-free mount...
Hello all,
I am trying to figure out a way to have Excel output possible gear ratio combinations of a limited set of gears.
The calculation would consist of number of teeth (N1) divided by number of teeth of another gear (N2) such that N1/N2 = Ratio1 while other iterations would add more...
