Exhaust header fatigue analysis

Exhaust header fatigue analysis

Exhaust header fatigue analysis

(OP)
I would like to use FEA to get a handle on the life expectancy of a cast stainless steel collector used on an exhaust header for light trucks and SUVs.  Will I need to consider inputs from both the suspension of the vehicle and the engine or just the suspension?

RE: Exhaust header fatigue analysis

You will need to consider vehicle G levels (pot holes, etc...),engine vibration, and thermal expansion. Most of the exhaust failures I have seem were due to thermal expansion. Good luck.
