我的理解是
运动学模型为无间隙模型,反应的是模型几何关系,忽略构件之间可能存在飞脱情况。好像考虑了阀系的总刚度。。
动力学模型要考虑从动件系统中各弹性构件产生弹性变形,可构件可看成弹性质点。
楼主可仔细看看tycon_appendixA的例子。
最后提到Never use the modification of cam profiles
without checking the valve train dynamics. Valve train
dynamics and excitation by the cam profile are closely
related. You need understanding of the dynamics of the
system as well as of the effects of changing the cam profile
to succeed in using this module
