摘要
针对CTC-1型工程洗轮机初期产品设计粗糙的问题,为使设计更加合理,采用结构有限元法分析方法,对构建的洗车平台模型进行有限元仿真计算。仿真结果显示,原工程洗轮机部分结构设计不合理和洗车平台尺寸设计过于保守,有较大的改进和优化空间。通过改变支撑的位置、形状、数量,改善了洗车平台的应力集中和使得支撑设置更趋合理;针对洗车平台尺寸设计过于保守的问题,提出了基于响应曲面法轻量化设计,在满足整体强度要求的情况下,洗车平台达到了轻量化的目标。
In this research, aiming at the problem of rough product design in the initial stage of CTC-1 wheel cleaing machine of engineering vehicle, in order to make the design more reasonable, The finite element method(FEM) was used to analyze the car cleaing platform model. The simulation results show that the structure design of the original wheel cleaing machine of engineering vehicle is not reasonable and the size design of the car cleaing platform is too conservative, so there is much room for improvement and optimization.By changing the position, shape and quantity of the support, the stress concentration of the car cleaing platform is improved and the support setting is more reasonable. Aiming at the problem that the size design of the car cleaing platform is too conservative, a lightweight design based on response surface method is proposed.
