介绍了内燃机配气凸轮从动件的运动曲线种类 ,研究了如何进行配气凸轮从动件运动曲线设计 ,提出了获得理想凸轮运动规律的方法In order to get optimal motion rule of ICE, the motion rule of cam is analyzed and the process of designing the motion curve of cam is researched. A method for designing the motion curve of cam is proposed. First, the combination motion rule of cam is put forward, then equality acceleration and equality velocity curve is used in amortizing sect of cam,and multinomial multi square curve is used in working sect of cam,but the motion parameter continuum at joining point must be insured. Finally, we draw the following conclusion: selecting the proper parameter in motion equation of cam follower can achieve the optimal motion rule of ICE.
