摘要
本文基于某新开发柴油动力皮卡车型,蓄电池、保险盒、ESP模块、燃油滤清器等部件均布置于机舱内左侧一线,面对机舱内紧凑布局要求状态,通过整车建模及CAE分析方法评估高速碰撞下机舱内线束安全性,识别到蓄电池正极线束受挤压问题后,提出若干改进方案,并通过仿真分析方法确定可行性方案,最后通过实车试验再次确认方案的可行性,使得机舱内线束在高速碰撞工况中的安全性满足设计要求。
This article is based on a newly developed diesel-powered pickup truck model,the battery,fuse box,ESP module,fuel filter and other components are arranged on the left side of the cabin.In light of the compact layout requirements in the cabin,the safety of the wiring harness in the cabin under high-speed collision is evaluated using vehicle modelling and CAE analysis methods.After identifying the extrusion problem of the battery's positive wiring harness,several improvement schemes are proposed,and the feasibility of these schemes is determined through simulation analysis methods.Finally,the feasibility of the scheme is reconfirmed through actual vehicle testing.The safety of the wiring harness in the cabin under high-speed collision conditions meets the design requirements.
