摘　　要：为优化汽车驱动盘性能,以某汽车驱动盘为例,对影响汽车驱动盘刚度和强度的显著因子进行筛选。以驱动盘盘体厚度、去重孔绕轴旋转角度、去重孔侧圆圆心距、去重孔侧圆半径、去重孔外圆半径及去重孔内圆半径等为因子,以驱动盘去重量为约束,轴向冲击0.5 mm疲劳分析、刚度分析、10倍转矩分析、13000 r/min转速离心力工况分析、0.5°失配疲劳分析最小化为目标,采用Plackett-Burman设计法建立优化试验模型并进行分析。结果表明,驱动盘厚度和去重孔绕轴旋转角度、去重孔侧圆圆心间距、去重孔侧圆半径是显著影响因子,经对该参数的优化,可提高驱动盘的刚度和强度性能。To optimize the performance of automotive flexplate,taking an automotive flexplate as an example,the significant factors influencing the stiffness and strength of the automotive flexplate are identified.Taking the thickness of the f lexplate,the rotation angle of the lightening hole around the axis,the center distance of the side circle of the lightening hole,the radius of the side circle of the lightening hole,the radius of the outer circle of the lightening hole and the radius of the inner circle of the lightening hole as the factors,the lightening weight of the flexplate as the constraint and the axial impactfatigue analysis of 0.5 mm,stiffness analysis,10 times torque analysis,centrifugal force condition analysis at a rotational speed of 13000 r/min and 0.5 mismatch fatigue analysisas the goals,the Plackett-Burman design is applied to establish the optimization test models for analysis.The results show that the thickness of the flexplate,the rotation angle of the lightening hole around the axis,the center distance of the side circle of the lightening hole and the radius of the side circle of the lightening hole are significant influencing factors,and the optimization of the parameters can improve the stiffness and strength performance of the flexplate.
