摘要： 换电是新能源重型商用车未来的发展方向，而换电模块的结构设计和轻量化是当前整 车设计中非常重要的部分。基于某重型商用车换电模块的风险工况，通过对模块框架结构拓 扑优化及尺寸优化，实现轻量化，对比发现，优化后的强度疲劳性能均有显著提升，并实现 整体减重 11.6%。对标市场主流竞品结构，对其强度疲劳性能进行评估，优化后的方案也优 于竞品。因此，方案优化经过有限元评估，换电模块架构性能指标满足设计要求，实现了轻 量化和降低成本，同时为其他同类车型的换电模块设计提供参照。

Abstract: Battery-swap is the roadmap of new energy heavy-duty commercial vehicles. The structural design and lightweight of battery-swap module is a very important part of the current vehicle design. Based on the worst cases of battery-swap module of a heavy commercial vehicle, the module frame structure topology optimization and size optimization are carried out to achieve lightweight. It is found that the strength fatigue performance after optimization is significantly improved, and the weight is reduced by 11.6%. Compared to the mainstream competitive products in the market, the strength fatigue performance of is evaluated, and the results so that the optimized scheme is also better than the competitive products. Therefore, by the use of finite element evaluation and scheme optimization, the performance of the battery-swap module architecture meets the design requirements, realize the lightweight and cost reduction, it also provides a reference for the battery-swap module design of other similar models.
