摘　　要：轻量化是提高新能源汽车续航里程的关键技术之一,确保制造成本轻量化之间的平衡,是各大车企面临的考验。通过收集、整理轻量化制造、装配和设计技术,从车身、内外饰、底盘及三电领域典型零件举例阐述可实现的技术方案。研究认为实现轻量化一般采用轻质材料替代和部件结构优化,其中钢铝混合车身、一体化压铸和零部件集成设计是目前热点,也是实现整车减重技术发展的方向。Lightweight is one of the key technologies to improve the range of new energy vehicles.How to achieve a balance between cost and weight reduction is a challenge faced by major car companies.By collecting and organizing lightweight manufacturing,assembly,and design technologies,feasible technical solutions are explained through examples of typical parts in the body,interior and exterior decorations,chassis,and three electrical fields.Research suggests that lightweight materials and component structure optimization are generally used to achieve light weighting.Among them,steel aluminum hybrid body,integrated die-casting,and component integration design are currently hot topics and also the direction for the development of vehicle weight reduction technology.
