某电动汽车驾驶员座椅后横梁平台化开发

Platform development on rear crossbeam of driver seat for an electric vehicle

针对电动汽车地板下方无法布置横梁、纵梁等结构,导致地板刚度较差的问题,在对比传统车型座椅横梁结构的基础上,提出一种贯穿式驾驶员座椅横梁结构。从刚度、模态、碰撞安全性能等角度出发,对座椅横梁结构进行优化设计。经有限元分析验证,优化后横梁结构在满足各项性能要求的同时可加工性也较好。该方法可为电动车座椅横梁平台化开发提供参考。

As to the problem that it is impossible to arrange cross beam and longitudinal beam under the electric vehicle floor,which lead to the floor poor stiffness,a through-type of seat cross beam for driver is proposed based on comparing with the traditional vehicle seat cross beam structure.The seat cross beam structure is optimized by considering the performance of stiffness,modal and collision safety.The design is verified by finite element analysis.The optimized beam structure meets all the performance requirements and has good machinability at the same time.The method can provide a reference for the platform development of the electric vehicle seat cross beam.
