Abstract:In order to study the feasibility of using a glass fiber reinforced composite to replace traditional metal material, the simulation analysis is made on Glass Fiber-Reinforced Polymer (GFRP) sector gear of Automated Mechanical Transmission (AMT) clutch actuator. First, the multi-body dynamics simulation software-ADAMS was used to analyze the load boundary conditions in the process of work. Then, considering the anisotropy of GFRP material, Moldflow, Digimat and Workbench software were coupled to analyze with simulation the dynamic stress of structure. The research results have a certain guiding significance for the study of structure stress of the same type fiber-reinforced material parts. Finally, the physical production of GFRP sector gear had been produced by using the injection molding process and compared with the traditional producing cost and weight of metal gear. The results indicate that the GFRP sector gear can not only reduce the cost by 79.3%, but also reduce weight by 58.9%, which fully shows the advantages of the GFRP gear sector instead of metal sector gear.
