摘　　要：以工程车辆所应用的经典伸缩式实腹臂体为研究对象,选取某系列高空作业车辆臂体截面的尺寸参数及臂体的应力极值为样本,用于BP算法,进行回归训练,获取系列臂体尺寸参数变量与结构应力极值的映射关系。设计人员可用该映射关系式快速预测结构应力极值,减少大量初步方案设计时的试错工作,为事前仿真提供设计依据,提高产品设计效率,快速响应市场需求。Taking the classical telescopic solidweb boom used in engineering vehicles as the research object,the dimensional parameters of the boom sections and the stress extremums of the boom of a series of aerial work vehicles are selected as samples and used in the BP algorithm for regression training to obtain the mapping relationship between the dimensional parameter variables of the series of booms and the stress extremums of the structure.Designers can use this mapping relationship to quickly predict the stress extremums of the structure,which reduces a lot of trial and error in the preliminary design,provides a design basis for presimulation,improves the efficiency of product design and responds quickly to market demand.
