摘　　要：由于振动传感器是摄取振动能量的,故传感器封装外壳会受到较为复杂的载荷作用,其在特定频率的共振现象时常发生,为避免由于外壳共振导致传感器摄取参数不准确,甚至造成传感器失效的情况,需要对外壳结构进行模态分析,掌握结构的固有频率。基于此,简要阐述了结构模态分析的基本原理,及使用ANSYS Workbench软件进行模态分析的基本步骤,并结合某型号的振动传感器的外壳实例进行分析,结果表明,使用ANSYS Workbench软件对设计结构进行模态分析,可以有效仿真出结构的振动特性,为传感器外壳结构设计提供简单而有效的方法。Due to the fact that vibration sensors absorb vibration energy,the sensor packaging shell can be subjected to relatively complex loads,and resonance phenomena at specific frequencies often occur.In order to avoid inaccurate sensor uptake parameters and even sensor failure due to shell resonance,it is necessary to conduct modal analysis of the shell structure to master the natural frequency of the structure.In view of this,the basic principles of structural modal analysis and the basic steps of using ANSYS Workbench software for modal analysis are briefly described,and an example of a certain type of vibration sensor housing is analyzed.The results show that using ANSYS Workbench software for modal analysis of the designed structure can effectively simulate the vibration characteristics of the structure,providing a simple and effective method for sensor housing structure design.
