【Abstract】 To solve the problem of dynamic balance training of human body,a 3-RSS/S parallel robot structure is proposed. The UG software is used to design a three-dimensional model of the mechanical structure of the parallel robot,and the model is imported into Msc.Patran. Based on the actual working conditions,the modal and stress analysis of the parallel robot is performed. Under the condition that the natural frequency of the typical position and the corresponding mode shape of the first three modes are obtained,a load is applied to calculate and analyze the maximum stress of gravity deformation and limit position. The experimental simulation results verify the rationality and reliability of the parallel robot design,and this design can meet the needs of rehabilitation training.更多还原
