Abstract

In order to realize the lightweight design of mobile pump truck, this paper takes the frame of a certain type of mobile pump truck as the research object. The response surface method is used to carry out lightweight design of the longitudinal beam structure of the frame, and the finite element method is used to establish the finite element model to compare and analyze the optimized and original designs. The results show that the height, width and thickness of the optimized longitudinal beam section are reduced by 10mm, 11mm, and 0.8mm respectively, and the weight of the whole frame is reduced by 35.8kg. Before and after optimization, the displacement and stress changes of the frame are small in four motion situations, which meet the lightweight requirements of optimization design.

为实现移动泵车的轻量化设计，本文以某型移动泵车车架为研究对象，采用响应面法对车架纵梁结构进行轻量化设计，并采用有限元法建立有限元模型，对优化设计和原始设计进行对比分析。结果表明，优化后的纵梁截面高度、宽度和厚度分别减小了 10mm、11mm 和 0.8mm，整车车架重量减轻了 35.8kg。优化前后，车架在 4 种运动工况下的位移和应力变化均较小，满足优化设计的轻量化要求。
