摘　　要：通过对复合二摆、正弦-抛物线、高次多项式3种非对称配气凸轮型线的仿真计算和分析,总结出了缓冲段终点速度、缓冲段终点升程、基本段半包角等特性参数的变化对几种凸轮型线和气门运动规律影响的共性和各型线自身的特征响应,为配气凸轮型线设计方案的选择和目标性设计调整提供了参考依据。By simulating, computing and analyzing FB2, sine-parabolic and high-order polynomial the cam profile of asymmetrical valve train, the influences of characteristic parameters such as velocity at the end of buffering zone, lift at the end of buffering zone, half-angle of base zone on the cam profile, and the valve movement as well as the self characteristic response of every cam profile were analyzed. The obtained results can provide reference for the design of cam profile of valve train.
