Typical dynamic loads generated by vehicle engine, driveshaft, and dynamometer
Typical dynamic loads generated by vehicle engine, driveshaft, and dynamometer
(OP)
I am designing several foundations to support dynamometers connected to vehicle engines by driveshafts. The purpose of my analysis is to minimize the vibrations transmitted to nearby sensitive equipment. My client has not provided the dynamic loads generated by the dynos, driveshafts and engines. Are there typical values for these parameters that could be used when this information is not supplied?

You should have the allowed vibration in function of frequency of the sensitive equipment, and can calculate the required damping from that.
Also, if you have 1 piece of sensitive equipment, and many dynometers, it is best to isolate the sensitive equipment.

Oh man. Are they planning to install all the roof mounted HVAC equipment directly over the president's office too?

What kind of engines are they testing? V8s? Inline 4? V twin? opposed cylinder? What RPM range?

How do you related the allowed vibration (which is a response change according to the foundation the equipment lays on) to dynamic load (which is usually constant regardless of foundation).
