惯性系统三轴测试转台内框形状优化设计

The optimal design of inner frame shape of a three-axis test turntable in inertial system

建立了惯性系统三轴测试转台内框形状优化模型和结构分析模型，采用连续体形状优化的罚函数方法进行优化设计。优化结果与理论分析一致，最优内框形状和国外转台形状相似。

The shape optimal design model and the structural analysis model of the inner frame of a three- axis test turntable in inertial system are established. The optimal design is carried out by adopting the penalty function method of continuous body shape optimization. The optimized result is consistent with the theoretical analysis,the optimal inner frame shape is similar to that of the test turntable existed abroad.
