摘要
众所周知,整车重量的减轻会直接影响到油耗,尾气排放量以及原材料的成本,而作为汽车行驶载体的轮毂轻量化设计已经成为未来汽车发展的必然趋势;基于Opti Strut优化求解器,考虑了冲击以及弯曲径向疲劳台架试验,对18X7.5低压铸造铝合金轮毂的正面造型以及背腔减重窝进行了拓扑优化设计,保证了台架试验的可靠性的同时,达到了轻量化的目的。
As we all know that reducing the vehicle weight will directly affect the fuel consumption, exhaust emissions and thecost of raw materials, so lightweight design of the wheel has being the trend in the future. In this paper, based on the OptiStrutsolver, the topology optimization for the front shape and loss weight pocket of the low-pressure casting aluminum wheel areconducted with consideration of the impact and bending and radial fatigue bench test. Thus it would ensure the reliability ofbench tests, as well as attaining the goal of lightweight design.
