| Summary: | Aiming at the problem of large deviation between the simulation results and the actual situation when regarding the pure rigid body as the smaller stiffness part with large force. Firstly,the working theory of auxiliary standing mechanism is sketched,then the rigid- flexible coupling dynamic simulation model is set up by utilizing the ADAMS and ANSYS. Based on the simulation model,the dynamic stress of upper and lower pipe in one movement cycle of the auxiliary standing mechanism is obtained,and the corresponding moment of the largest stress in the whole time course is further determined,then it is compared with the dynamic stress calculation results of the corresponding time in Workbench. The research results show that under the condition of the permitted error,the two results are basically consistent. The accuracy of theoretical calculation dynamic stress method based on the rigid- flexible coupling dynamics simulation model is verified,as the same time,compared with the finite element method,the analysis result of rigid- flexible coupling model can reflect the real dynamics behaviors of mechanism. |
