摘　　要：建立恒力弹簧支吊架壳体仿真模型,计算恒力弹簧支吊架壳体在不同工况下应力情况。从改变刀型凸轮安装方式、减小钢板厚度、拓扑优化恒力弹簧支吊架壳体支撑脚三方面对壳体进行优化改进,并对轻量化处理后的壳体进行疲劳损伤验证。最终优化了壳体结构,提高了恒力弹簧作用过程中的稳定性、准确性。In this thesis,the simulation model of the constant force spring support hanger shell is established,the stress of the constant force spring support hanger shell is calculated under different working condition.The installation method of the knife cam,the reduction of the thickness of the steel plate,the topology optimization of the support leg of the constant force spring support hanger shell are optimized and improved,and the fatigue damage of the lightweight shell is verified.ultimately,the shell structure is optimized,and the stability and accuracy of the constant force spring are improved.
