What I can add so far, or what I have tried before is the following (which didn't help me a lot): Energy or work is defined as follows (units in [ ] ): W = F*s = [N]*[m] with: [N] = [kg * m/s^2] work follows: W = [kg * m^2/s^2] So work "W" per mass "m" is: W/m = [m^2/s^2] Now my problem is...

Hello Everyone I have got a question concerning the calculation of the overall energy input in random vehicle vibration tests. I have got different power spectral density levels for different random vehicle vibration tests and would like to compare them with each other concerning the overall...

Hi Everyone Just want to introduce myself quickly: I'm a mechanical engineer and mainly have experience in numerical structural analysis while my focus in previous years was on strength assessment of metallic structures for railway vehicles. Lately I have changed the scope quite a bit and...
