摘要

为了保证结构在强度和稳定性不减弱的前提下达到轻量化的效果,以某车企自主研发的新型2AT变速箱壳体为研究对象,建立其有限元模型并对它进行静力分析和模态分析。然后基于分析结果,以位移、应力、一阶固有频率和体积比为约束,以组合应变能指标为目标对壳体进行动静态联合拓扑优化。最后基于优化结果,综合考虑制造工艺等要求对结构进行详细的改进设计。改进后的结果表明:结构强度和一阶固有频率均得到有效改善,同时变速箱壳体质量由8.238 kg减为7.529 kg,减轻了8.6%,达到了轻量化的目的。

Abstract

In order to achieve the effect of lightweight under the premise without weaken strength and stability of the structure,the main research object is based on the 2 AT gearbox which comes from the independent research and development of a car enterprises,establish its finite element model and its static analysis and modal analysis are carried out. Then,based on the analysis results,the stress,displacement,volume ratio and the first order natural frequency are the constraints. Finally,according to the optimization results,considering the manufacturing process and other requirements,the structure is improved in detail. The improved results show that the structural strength and the first order natural frequency are effectively improved,and the mass of the transmission case is reduced from 8. 238 kilogram to 7. 529 kilogram,which is reduced by 8. 6%,lightweight is realized.
