车身轻量化系数的决定因素及其优化

介绍了车身设计评价的关键指标-车身轻量化系数,阐述了车身轻量化系数的优化方法,即减轻车身质量和提高扭转刚度.指出,应主要从钢材选择、结构设计、新技术新材料的选用等角度实现车身质量减轻;主要通过车身加强件增加或板材加厚、车身高强度板用量提高、结构断面优化、车身接头设计优化等方法提高车身扭转刚度.

Investigation on Body Lightweight Design Method

Body lightweight coefficient is introduced in this article as a key factor for body design evaluation. An optimized method of body lightweight, e.g. weight saving & stiffness improvement are presented. It is pointed out in the paper that body lightweight should be realized mainly by steel selection, structural design, selection of new techniques and new materials; whereas body torsion stiffness can be improved by adding body reinforcements or thickening steel sheet, increasing the amount of high strength st...
