Design and Simulation of a New Type of Electromagnetic Locking Mechanism

The aims of this study were to design a new type of electromagnetic locking mechanism for automated packaging of the product, and to conduct simulation analysis on the performance of the electromagnetic locking mechanism. The establishment of the 3D model and dynamic simulation of the mechanism was carried out by using UG and ADAMS mechanical dynamics simulation software, the motion law and dynamic curves on electromagnetic locking mechanism were obtained at the same time. The simulation results showed that when the speed increased by 5 mm/s each time, the contact force between locking mechanism and the adsorption block body would increase by about 15 N, meanwhile, backward displacement on adsorption block would increase by approximately 1.7 mm. Through the analysis, reasonable control of the speed can effectively improve stability of the system. The result showed the motion law and dynamic curve of the system were obtained to verify its feasibility, indicating ADAMS can offer strong evidence on motion law and prediction feasibility of the complex system.
