在完成对某同轴回转式测量系统中回转装置的初期设计基础上，对其中回转装置进行模态分析，结果显示回转装置第一阶模态频率偏低，为避免其与检测现场激振频率发生共振，并提高检测精度，提出采用 Workbench 中灵敏度分析的方法，对回转装置结构进行优化，得到了回转装置的最佳设计方案。研究结果对提高系统精度，防止共振的发生等方面具有重要意义，为进一步的设计改进工作提供很好的理论支持。

The paper based on the initial design of the swing device in a coaxial rotary measurement system, and the result of the modal analysis on the swing device shows that the first-order mode frequency of the swing device was low. In order to avoid the resonance between the swing device and the excitation frequency of detection field,and improving the accuracy of detection,we optimized the construction of the swing de-vice by means of sensitivity analysis in the Workbench. In this way we obtained the best design project of the swing device. The research has important implications for improving the accuracy of detection and preventing resonances,and gives well theoretical support for the further design improvements.
