本文主要叙述链传动系统的模型化方法及其计算机动态模拟,即在将链传动系统模型化为四杆机构基础上建立计算画法几何模型,再根据链传动的运动方程建立动态模拟的数学模型。 This article mainly describes the modeling method of chain drive system and its computer simulation. That is to say, the model of the chain drive system is modeled as a four-bar mechanism, and the geometric model of the calculation method is established. Then the mathematical model of dynamic simulation is established according to the motion equation of chain drive .
