摘　　要：由于汽车驱动盘上信号缺齿和定位销孔的存在,使其结构不规则,影响工作中的动平衡,进而影响其性能。为提高汽车驱动盘刚度强度性能,以某汽车驱动盘为研究对象,提出基于响应面法的结构优化设计方法。以驱动盘盘体厚度、去重孔旋转角度、改去重孔个数和改孔半径为设计因子,以驱动盘去重量为约束,以轴向冲击0.5 mm应力最小化为目标,运用最小二乘法,建立响应面优化模型。试验结果表明,采用该方法能够满足不平衡量要求,最大应力减小了26.79%,提高了驱动盘轴向冲击疲劳强度。The existence of dowel hole and lacking of signal gear teeth,making flex-plate structure irregular,have an impact on dynamic balance,which affects the property of flex-plate.Taking a certain flex-plate as an example,it was optimized by response surface method to improve the stiffness and strength property.The optimized model was built using least-square method,with the design factors of the change of flex-plate thickness,the rotating angle and the number of changed holes,and radius of the holes,constrained by removing weight,targeted as minimizing the stress of 0.5 mm axial displacement.The test showed that,this method could meet the requirement for removing weight,the maximum stress was reduced by 26.79%,obviously,axial fatigue strength of the flex-plate was improved.
