摘　　要：本文基于COSMOSWorks有限元分析模块,对三轴稳定平台的外框进行了静力和模态分析,并以外框的转动惯量为目标函数,以外框的尺寸、应力以及一阶固有频率为约束条件,建立了外框的优化数学模型,最后由COSMOSWorks计算出优化结果,从而实现了平台机械系统的优化过程,同时也说明了基于有限元理论的优化设计在现代机械设计中起着重要的作用。This paper has studied the structure stress and modal analysis of three-axis table on the basis of COSMOSWorks FEA module.An optimal mathematic model, which has been built by taking the moment of inertia of frame as objective function, the structural dimensions, stress and the first inherent frequency as constrained condition, is resolved correctly by COSMOSWorks. This shape optimal design of mechanical system of table shows that FEA optimum design plays an important role in the modern mechanical design.
