纺织机械用联轴节的转子振动特性

The Vibration Characteristics of Rotors Connected with a Flanged Coupling in Textile Machinery

研究纺织机械中具有凸缘联轴节的转子的振动特性。列出了具有联轴节的振动微分方程。其方程是参数激励和强迫激励联合作用。应用非线性振动的理论 ,用傅里叶展开求得其稳定响应 ,得到了非常有用的结果。这些结果对研究具有联轴节的轴的故障机理以及纺织品及半成品的质量控制。

In this paper,the vibration characteristics of rotors connected with a flanged coupling in textile machinery are studied.A proof is given to show that misaligned rotors produce vibration frequencies of odd number times shaft speed.The conclusion is very important and useful.The experimental results of the rotor system test are in agreement with the theoretical analysis.
