Abstract Injection manipulator is a production equipment to automatically control the plastic processing. In practical work process， injection manipulator generates structure resonance in condition of fast response. It affects the positioning accuracy of manipulator. Parametric modeling method and CAE software were used to conduct the structure resonance finite element analysis of injection manipulator. Based on the multidisciplinary optimization design platform， with the aim of reducing resonance， the adaptive simulated annealing method was adopted to the optimization design in respect of the structure and the size of injection manipulator. Results show that， manipulator platform vibration is reduced， the positioning accuracy of manipulator is improved， and the automation of the optimization design process is realized， thus a systematic reference for the design of similar production is provided．

基于结构谐振CAE分析的注塑机械手优化设计
注塑机械手是对塑料加工生产进行自动控制的生产设备.在实际工作过程中，注塑机械手在快速响应的控制条件下会产生结构谐振，影响机械手的定位精度.应用参数化建模方法和CAE软件对注塑机械手进行结构谐振有限元分析，并基于多学科优化设计平台，以减小谐振为目标，采用自适应模拟退火算法对机械手的结构尺寸进行优化设计，最终降低了机械手平台振动，提高了机械手的定位精度，并实现了设计优化过程的自动化，为类似产品的设计开发提供了系统的参考方法.
