| 中文摘要: |
| 当前外部经营环境对车企来说一直不是很理想,同时各个车企之间的竞争已经进入了白热化阶段,也导致了利润的降低。为了降低造车成本,考虑将电车的铝合金电池包换成钢制电池包,但通过整车侧柱碰工况仿真分析发现：由于钢制电池包质量的增加,该工况中,车辆侧围变形严重且电池包的外壳变形过大,车辆存在热失控风险。为了提高车辆的耐撞性和底部电池包的安全性,选取门槛梁厚度为优化参数,基于正交试验法,对车辆进行仿真分析,以找出最优方案。然后将钢制电池包与铝合金电池包从多角度进行对比分析,阐述各自的优势,为后续车企针对不同车型选取不同材质的电池包提供了依据。 |

| The current external business environment has not been ideal for car companies, while the competition between various car companies has entered a white-hot stage, which has also led to a reduction in profits. In order to reduce the cost of the vehicle, the aluminium battery pack of the tram was considered to be replaced by a steel battery pack, but the simulation analysis of the whole vehicle side pillar collision condition found that: due to the increase in the mass of the steel battery pack, the vehicle side surround deformation is serious and the shell of the battery pack is deformed too much in this condition, the vehicle has thermal runaway risk. In order to improve the crashworthiness of the vehicle and the safety of the battery pack at the bottom, the thickness of the threshold beam was selected as the optimisation parameter and the vehicle was simulated and analysed based on the orthogonal test method in order to find the optimal solution. The steel and aluminium battery packs are then compared and analysed from multiple angles to illustrate the advantages of each, providing a basis for subsequent vehicle manufacturers to select different materials for different models of battery packs. |
