The joint simulation of mechanics and kinematics was carried out for a certain model of row straightening machine plaque.Using ANSYS software,a finite element analysis model of the plaque was constructed,the stress field and displacement field of the plaque were calculated in detail,and according to the relevant national design standards,the kinematic analysis was carried out by using Recurdyn software,the results show that the contact between the plaque of the row straightening machine and the bearing seat is close to the actual working conditions,and the results of this analysis provide a valuable reference for the structural design and optimization of the plaque of the row straightening machine.The analysis results provide a valuable reference for the structural design and optimization of the row straightening machine plate.
