engine and ride vibration calculation
engine and ride vibration calculation
(OP)
Hi,
I'm sure this question will seem pretty basic for most here but I'm not particularly familiar with vibration and would really appreciate pointing in the correct direction.
I'm trying to set up a test whereby i will test different sensors using different vibration frequencies. The idea is to attempt to find if the sensors (which will eventually be used for race vehicle acquisition) read the same whether they are in vibration or steady. The problem is that I want to calculate the realistic vibration. I need to work out firstly, engine vibration from a theoretical engine that im basing the test upon. Secondly i need to work out the road vibration or wheel induced vibration. I know the potential gearing, wheel speeds, wheel sizes and rpm.
How might I go about doing this, any help is appreciated.
Thanks

RE: engine and ride vibration calculation
I'm not looking to work out the exact vibration as i know you would have to work out the vibration through materials etc.
Is there a relatively simple method of working out what vibration would potentially come from the engine/gearing and the road due to bump??
Thanks
RE: engine and ride vibration calculation
Your best answer is probably to instrument a variety of vehicles driving over the specific surface of interest, envelope the response, and generating PSDs from the measured data.

RE: engine and ride vibration calculation
typical body vibrations are less than 1g, don't have a good feel for the numbers.
typical suspension vibrations might be 10g peak in a curb strike, very roughly.
