一种平面四杆机构的运动学分析

摘要

探究一种平面四杆机构的运动特征，分别用矢量方程图解法和ADAMS软件对其机构运动情况进行分析，得到机构运动过程中各杆件速度、加速度变化曲线，并分析其变化规律。研究结果表明：仿真方法可以获得机构整个周期的全过程值并且精度较高，矢量方程图解法只能获取机构某位置的运动特性，若需要其他位置值，则需反复做图求解。%To explore the motion characteristics of a planar four bar mechanism, this paper analyzes the motion of the mechanism using the vector equation graphic method and ADAMS software, obtains the velocity and acceleration curves of the mechanism and analyzes the change law. The research results show that the simulation method can obtain whole process value of the whole cycle and precision is high, the graphical method of vector equation can only obtain the motion characteristics of a certain position, if you need other position value, you need to do this chart another time.
