Summary:

Using an implicit transient FEA models of an intake engine valve, the dynamic stress/strain response of a valve closing (impact) on the valve seat was simulated. Key dynamic events during the closing process were identified and their corresponding physics accounted for in the model including: valve seat contact, valve tilt, rocker arm separation, material properties, shock wave and stem seal damping.Empirical tests were conducted to characterize the stem seal damping as a function of valve stem velocity. In addition, a simplified dynamics equation approach was developed. The results were successfully correlated to recorded strain gauge data
