摘要
为了使车架在满足使用强度要求的前提下重量最轻,以车架最大应力作为车架优化设计性能约束,以车架的轻量化作为目标函数,建立了SUV型汽车车架设计空间。实验表明:车架重量减轻了26.5%,优化效果明显。
In order to make the frame to meet the strength requirements under the premise of the lightest weight, the frame of an SUV Design Space is established by using the maximum stress of the frame as the frame optimization design performance constraint, lightweight frame as the objective function,. The results of the analysis provide a feasible routes and new ideas for optimal design of the frame..
