摘　　要：应用Excite_TD软件,对某发动机配气机构进行运动学和动力学分析,保证气门良好、准确、平稳的运动规律下,重新设计了凸轮型线,优化后的凸轮型线,经过发动机试验验证,具有良好的运动学和动力学特性。With the application of Excite TD software,the kinematics and dynamics analysis of the valve mechanism of an engine was carried out.Under the condition that the valve was good,accurate and flat floor motion law,the CAM profile was redesigned.The optimized CAM profile was verified by engine test to have good kinematics and dynamics characteristics.

关 键 词：配气机构 凸轮型线 运动学 动力学
