摘　　要：模态综合法对复杂结构在复杂工况下的动力学分析比传统模态分析更能接近于现实。用Pro/E和ANSYS软件对高速飞行的数控模拟转台进行建模及模态综合分析,得出该装配体的六阶模态图,并与一般模态分析比较,得出上述结论。The Modal analysis＆ modal synthesis of the three-axis turntable were made by using Pro/E ＆ ANSYS software,Then the relevant mode graphs ＆ frenquency were obtained, thereby providing the manufacturer with detailed and reliable data. The conclusion is the modal synthesis is more effective in this kind of structure.
