A Dynamic Analysis of Valve Mechanism of High-Speed Engine Using FEM

This paper presents the analytical studies on the stress and strain of driven valve system of internal combustion engines. The stress and strain is predict using FEM. The particular interest is the dynamic strain at a specific point of the valve and valve seat. Cam and follower Assuming that one rigid surface. This study forced the effects changing Young's modulus and density of valve and valve seat contact area. It supports that the indirect method using FEM is reliable for prediction the actual displacement, stress and strain in the valve system.
