Outline
Due to the significant difference in the position of the body pivot holes between the new model produced in an assembly workshop and the original one, the existing spreader can’t meet the production needs. Therefore, a solution is proposed to achieve co-production of 2 platform vehicle models by replacing the lifting fulcrum and rear support arm. This solution greatly reduces the modification workload of spreader and the impact on related equipment, shortens the spreader modification cycle, and reduces the cost in integrating new vehicle models. Based on the ANSYS simulation platform, the stiffness and strength analysis of the modified spreader under static and dynamic working conditions are carried out. Online no-load operation testing and vehicle assembly testing are carried out on the spreader samples. The results show that the modified spreader can meet the co-production needs of this dual platform models.
