Abstract
Abnormal valve gear vibration is a perennial problem confronting the designer of high-performance 4-stroke engines.
It would shorten time and reduce costs if an analytical method could be applied to the prediction of engine valve behavior.
This paper describes a method of valve motion simulation for both SOHC and DOHC valve gears through interactive calculation and using computer graphics.
The authors tried to set up as simple a simulation model as possible by using modal analysis and modeling techniques.
Through setting simulation model parameters and experimental damping factors, a close correlation between calculated and actually measured results was found.
