摘要
针对320 t五轴线电动轮矿用车的行走机构进行轻量化设计研究。对宽距双胎行走机构及其零部件进行受力分析,针对电动轮驱动桥结构提出了一种分层拓扑优化设计方法,并对桥壳和摆臂进行拓扑优化设计及可制造化处理。研究结果表明,轻量化结构和原结构相比质量分别减轻了43.3%和36.3%,取得了明显的轻量化效果,提出的分层拓扑优化设计方法是非常有效的,对重型车辆的驱动桥壳设计有较好的应用价值。
The lightweight design and study of the 320 tons five-axis electric wheel miner truck travel agencies were performed in this paper. Stress analysis of the double wide wheels and travel part were performed. A layered topology optimization design method was proposed for the drive axle of the electric wheel, The bridge shell and swing arm were performed topology optimization and manufactured process. The results showed that the lightweight structure was reduced by 43.3% and 36.3% respectively compared with the original structure, which achieved the good effect of lightweight. The layered topology optimization design method was very effective. It was applicable effective for the drive axle of heavy vehicles.
