摘　　要：根据要求优化连杆结构,使之满足刚度、屈曲、疲劳要求。结构优化难点在于该连杆有两项屈曲要求:连杆轴向屈曲和减振器垂向屈曲。结构屈曲载荷目标值在某载荷区间内,上限值与下限值相差很小。结构静刚度和疲劳性能要求结构越强越好,屈曲性能要求结构不能太强,需要平衡各性能要求。According to the requirements of OEM,the link is optimized to meet the targets of stiffness,buckling and fatigue.The difficulty of structural optimization is that the link has two buckling requirements:axial buckling and vertical buckling of damper connection.The target of the buckling load is a range that is a small value.To achieve the targets of stiffness and fatigue,the structure need to be strong.However,the buckling performance requires that the structure can not be too strong.All the performance need to bebalanced of thelink.

关 键 词：连杆 结构优化 屈曲 疲劳 成本
