摘要
纯电动客车骨架轻量化对于提升其续驶里程具有重要作用。本文首先基于变密度法对整车骨架进行拓扑结构优化,然后通过灵敏度分析和尺寸优化方法对骨架主要杆件的厚度进行优化。经过综合优化后的某纯电动客车骨架的刚强度性能均有提高,且减重效果明显。
The lightweight of framework for a pure electric bus plays an important role in improving its driving range.Firstly,the topology of the vehicle framework is optimized based on the variable density method.Then the thickness of main bars of the whole framework structure is optimized by the sensitivity analysis and size optimization methods.After comprehensive optimization,the rigidity and strength performances of the pure electric bus framework are improved with an obvious weight reduction effect.
