摘　　要：汽车传动轴结构的常规设计有较大的结构强度过剩,根据传动轴在车辆运行过程中的受载特点和结构强度的演变规律,通过适当减小结构尺寸,合理提高使用应力,使其具有较低的初始设计强度,在使用过程中经受载荷的不断强化,强度潜力得到充分发挥。在结构优化过程中,以最佳累积强化效果为目标,根据设计应力分布区间与结构低载强化特性区间的对应关系来获取结构尺寸参数。最后通过传动轴零件的建模与仿真分析,验证了结构轻量化设计的有效性。Usually the structural strength for vehicle shaft is greater excess in conventional design.Based on the load characteristics and evolution of structural strength of drive shaft during vehicle operation,lower strength in initial design stage was optimized through reducing the section size and increasing the structural stress appropriately.With continuous strengthening of low-amplitude loads,the potential strength of shaft structure was given full play.In structural optimization by taking the cumulative effect of strengthening as target,the structure parameters were obtained according to the corresponding relationship between distribution of design stress and strengthen range of structure features.Finally,through modeling and simulating for the drive shaft,the effectiveness of structural lightweight design was verified.
