带凸缘联轴器振型的数值模拟

With Flange Coupling Vibration Model of Numerical Simulation

凸缘联轴器是机械中常见的一种联轴器,使用过程中其振动和噪声是我们要考虑的因素之一。零件的固有频率是其固有属性,一般与材料的刚度、结构等有直接关系,通过有限元分析软件Abaqus能很好的确定凸缘联轴器的固有频率;在使用过程中避开或最大限度的减少对这些频率的激励,防止凸缘联轴器长期在共振频率下工作,从而降低振动和噪声,同时还可以有效防止结构因共振而提前破坏。

Flange coupling is a common coupling in the machinery, the vibration and noise in use process is one of factors to consider.Natural frequency is its inherent attributes of the parts, general and material is directly related to the stiffness, structure and so on, through the finite element analysis software Abaqus can determine the natural frequencies of the flange coupling;In use process to avoid or minimize the frequency of the excitation, prevent the flange coupling long-term work under resonant frequency, reducing vibration and noise, but also can effectively prevent the structure damage in advance by resonance.
