摘要
为设计开发一种新型电动汽车车身,给出该小型电动汽车车身设计过程的架构方案,提出设计过程中实现尺寸、性能、重量等目标的管控方法。为确保汽车车身各项性能目标的实现,采用CAE仿真技术进行多维度分析评估,将车身性能立体化呈现,及时发现风险点,并进行同步修正设计,得到良好的车身结构。在重量控制方面,通过多材料、多工艺的应用实现车身的轻量化,初步完成该型电动汽车的钢铝混合车身设计,为该新型电动汽车车型量产提供理论依据。
In order to design and develop a new type of electric vehicle body structure, an architectural scheme for the design process of the small electric vehicle body is presented, and some control methods for achieving dimensions, performance, weight, and other objectives in the design process are proposed. To ensure the realization of various performance objectives of the car body, CAE simulation technology is used to conduct multi-dimensional analysis and evaluation, the body performance is presented in three dimensions, risk points are discovered in time, and synchronous correction design is performed to obtain a good body structure. In terms of weight control, weight reduction of the vehicle body is achieved through the application of multi-material and multi-process. The preliminary design of the steel-aluminum hybrid vehicle body is completed, which provides a theoretical basis for the mass production of the new electric vehicle model.
