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?

RE: Typical dynamic loads generated by vehicle engine, driveshaft, and dynamometer

Get the relevant norm (e.g. ISO 8528-9 for gensets, for sure there is an ISO / EN or other for your specific application) which gives the maximum allowed vibration, and use that one for your layout.
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?

RE: Typical dynamic loads generated by vehicle engine, driveshaft, and dynamometer

Tmoose, think along the lines of an emissions bench on the floor outside of the cell. Have you ever seen a dynamometer excite a natural frequency in the floor that it sits on?

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