Abstract：In order to analyze complex forward kinematics problem of 3-PRS parallel mechanism,a combination of positive solutions is solved by the numerical method,the forward and reverse kinematics mathematical model is established,and the forward kinematics is analyzed,3-PRS parallel mechanism configuration for forward kinematics is obtained. The results show that the calculation and simulation results are in agreement with the actual situation,and it lays a foundation for further study of the 3-PRS parallel mechanism.
