摘要
用有限元分析方法在动态分析的基础上,以各框架的转动惯量为目标函数,以框架尺寸和一阶固有频 率为约束条件,建立了三轴飞行模拟转台各框架的优化数学模型,采用ANSYS的APDL参数化设计语 言将有限元分析与优化设计有机结合起来,编制了用于复杂结构的优化设计程序,实现了自动的优化 设计过程。
This paper using finite element analysis method, On the basis of finite element analysis, taking the moment of inertia of each frame as objection functions, the structural dimensions and 1st inherent frequency as constrained condition, ANSYS parametric design language was introduced to combine the finite element method with the optimum design appropriately. This dissertation achieves optimum design of table frames by programming optimum design applied in a complicated structure.
