倾斜安装电机振动特性研究

因为安装空间和实际运行的需要，电机在倾斜工作状态下容易产生振动超标。该文针对倾斜安装异步电机结构特点，设计了倾斜安装异步电机的振动特性实验装置，分析了含有减振垫的异步电 机系统刚度特性，通过有限元分析计算出了不同厚度减振垫的刚度系数。实验中，采用不同厚度橡胶减振垫进行振动测试分析，结果显示，在倾斜 5°的安装条件下，异步电机共振转速随减振垫刚度的减小而明显减小。该研究结果可为倾斜安装电机与减振器振动特性匹配、设计与安装提供理论参考。

Research on Vibration Characteristics of Tilted Induction Motor

Subject to the space of installation and working condition, tilt-mounted asynchronous motor is prone to excessive vibration. In this paper, an experimental device is designed to investigate the vibration characteristics of tilt-mounted asynchronous motor by considering its structural characteristics. The stiffness characteristics of asynchronous motor system with vibration damping pad are analyzed firstly. Finite element analysis is used to calculate stiffness coefficient of vibration damping pad with different thickness. In real experiments, different thickness of rubber vibration isolation cushion are used for the vibration test and analysis. And the experimental results show that, the resonance speed of asynchronous motor decreases with the reduction of vibration damping pad stiffness, while the tilt angle of 5° is adopted. This conclusion can provide guidance for the design and installation of tilt-mounted asynchronous motor and shock absorber.
