一种空间四杆机构的运动学分析及仿真

Kinematics and Simulation for a Spatial Four-Bar Likage

本文对于空间四杆机构RSSR机构进行了分析,给出了该机构的自由度计算公式,并且计算了该机构的自由度。利用矢量的方法对于RSSR机构的运动学方程进行了推导,给出了这种机构的速度和加速度的计算公式。利用软件对于RSSR机构进行了运动学仿真,得到该机构的速度和加速度曲线。

The spatial RSSR mechanism is analyzed in the paper, and gives the formula of the degree of freedom, and calculates the degrees of freedom. The RSSR mechanism kinematics equations are deduced by vector method, gives the calculation formula of the velocity and acceleration. Using software has carried on the kinematics simulation for RSSR mechanism, get the speed curve.
