摘要

汽车吸能盒是整车重要的缓冲吸能结构。管件液压成形零件具有重量轻、刚度和强度高、耐撞性能好等优点,设计管件液压成形吸能盒替代原始冲压吸能盒。采用数值模拟方法分析吸能盒吸能性评价指标,比较管件液压成形吸能盒与冲压吸能盒缓冲吸能的性能。设计吸能盒的管件液压成形加载路径,通过成形分析得到加载路径对吸能盒的壁厚分布影响较大。故以吸能盒成形后的最小壁厚最大化作为优化目标,选取加载路径上的压力控制点作为设计变量,采用部分因子方法设计试验,然后采用克里格空间局部插值法构建近似模型,最后利用遗传算法求解得到优化后的加载路径,成功增加了吸能盒成形后的最小壁厚。

Abstract

The automobile crash box is an important buffering and absorbing energy structure.Due to the advantages of light weight,high stiffness,high strength and good crashworthiness for hydroforming tubular,the hydroforming crash box is designed instead of the stamping and welding structure.By numerical simulation,analysis the crash box key energy absorption properties,comparison of tube hydroforming crash box and stamping one absorbing performance.Design the load-curves for Tube Hydroforming automobile crash box,which is influence the crash box thickness distribution after forming.In this paper,maximizing of the minimum wall thickness of crash box after hydroforming is used as the research object,select the pressure control parameter on the load-curves as design variables,using fractional factorial designed experiment,then use of Kriging spatial interpolation method to build approximation model,Finally,the use of genetic algorithm to obtain the optimized loadcurves,increasing the minimum wall thickness of crash box after hydroforming.
