摘要 车身结构刚度对于车身的诸多性能有较大影响,目前的车身刚度研究方法难以量化车身关键区域承载大小且缺少不同区域刚度设计合理依据。本文提出基于均匀应变能密度的车身结构刚度设计方法,对某车型进行应变能分析并计算关键结构区域承载系数,根据承载系数找出薄弱区域和刚度偏强区域进行优化,并对优化后的车身结构进行分析。结果表明,优化后的车身结构刚度更加均匀化,基于均匀应变能密度的车身结构刚度设计方法能有效量化车身结构关键区域的承载大小,指导车身关键区域的刚度设计。 the stiffness of vehicle body structure has great influence on many performances of vehicle body. The current body stiffness research methods is difficult to quantify the load of the key area of vehicle body, and lacks reasonable basis for the stiffness design of different area. In this paper, the design method of body structure stiffness based on homogeneous strain energy density is proposed, the strain energy of a vehicle is analyzed and the load coefficient of key structural area is calculated. According to the load coefficient, the weak area and the strong stiffness area are found out and optimized, and the optimized body structure is analyzed. The results show that the stiffness of the optimized body is more homogeneous. The stiffness design method based on the homogeneous strain energy density can effectively quantify the load of the key area of body structure, and guide the stiffness design of the key area of body.
