摘　　要：对超高加速度宏微运动平台柔性定位平台的连接臂进行优化设计,以提高定位过程中的稳定性和寿命。在SolidWorks中构建三维模型,将模型进行参数化后导入Workbench中,通过静力分析得到最大总变形云图和等效应力云图,通过nCode模块得到疲劳寿命云图,从而得到连接臂的危险部位;对危险部位进行优化设计,通过响应面优化法选择优化参数和优化目标;最后,从优化方案中选取最佳方案进行验证。结果表明:最大总变形降低1.1%,优化后的连接臂等效应力降低16.3%,疲劳寿命提高30.4%。通过响应面优化方法很大程度上提高了超精密定位平台的稳定性和安全性。The connecting arm of the ultra-high acceleration macro and micro motion platform's flexible positioning platform was optimized to enhance its stability and lifespan during the positioning process.3D model was constructed in SolidWorks and parameterized before being imported into Workbench.Static analysis was conducted to obtain the maximum total deformation and equivalent stress cloud diagrams,and the fatigue life cloud diagram was obtained through the nCode module to identify the critical areas of the connecting arm.The critical areas were then optimized using the response surface optimization method to select the optimization parameters and objectives.Finally,the best optimization scheme was selected for verification.The results show that the maximum total deformation is reduced by 1.1%,the equivalent stress of the optimized connecting arm decreases by 16.3%,and the fatigue life increases by 30.4%.The response surface optimization method significantly improves the stability and safety of the ultra-precision positioning platform.
