Structural optimisation design of impact resistant composite wheel with compression/injection moulding hybrid structure

Based on the advantages of continuous fiber reinforced and long fiber reinforced injection molding composite wheels, a composite wheel with pressure injection hybrid structure for passenger cars is designed. First, based on the equivalent static load method, the topology of the wheel spokes is optimized under the 13-degree impact dynamics condition, and the initial structure of the wheel is obtained. Then, by analyzing the stress state and failure mode under the impact load, the stiffness matching design of the spoke section is carried out to determine the location of the layer and the material ratio. Finally, the parameters of the wheel are optimized, and the final structure of the wheel is obtained. The results show that the optimized wheel can pass the 13-degree impact test, and the weight of the optimized wheel is reduced from 4.61 kg to 3.921 kg.
