Car Acceleration profile

[scottjc]

Hi guys

I have been set the task of replicating the vibration levels seen on a car exhaust for a demo piece. Does anyone know where i can get a PSD profile to replicate these levels on a small shaker?

thanks

scott

No, but if it is a 4 cylinder with no balance shaft then the engine will be shaking at 20 g rms at 200 Hz, typically. You may have an exhaust decoupler in there to consider tho.
