摘要：
In this paper a dynamic model of cam-follower-rocker-valve system is presented. The lumped parameters model is with 8 degrees of freedom. Camshaft eccentricity and cam profile errors are also modeled and can be introduced in the model to observe their influence. The numerical simulation shows a fluctuation on the acceleration of the valve induced by the motion law exerted by the cam follower mechanism. The presence of eccentricity on camshaft showed a slight influence on the dynamic behavior whereas the cam profile error showed a substantial increase in the vibration levels.
