Optimized body structure and packaging for car ODB impact performance
Pages: 43-46
Year: Issue:  6
Journal: Engineering Sciences

Keyword:  packaging offset deformable barrier impact body structure crash performance optimization;
Abstract: <正>Front bumper,crash box and side rail are key body structural parts in front crash.Deformation space is affected by compartment packaging.The improvement suggestions are proposed to solve the problems existed in the current vehicle structure and compartment packaging based on the areas that influence performance of automobile offset deformable barrier impact, such as the side rail,mounting,storage battery packaging,etc.It is proved that 40%offset crash simulation result of one certain car is well-correlated with the physical test.Optimization cases meet the crash performance requirements.The objective of the analysis is to guide structural design and improves a car’s crash safety performance.
