摘　　要：通过Catia软件建立十字轴式万向联轴器三维模型,基于Abaqus有限元分析法,研究万向联轴器的振动特性。通过模态分析,求解得到万向联轴器前六阶固有频率以及振型,与稳定运行的电动机转动频率相比较,可知该万向联轴器并不会发生共振现象。通过静力学分析,求解得到十字轴式万向联轴器及十字轴、叉头的最大应力值与最大位移值,通过计算十字轴与叉头的许用应力值,与最大应力值进行比较,可知该万向联轴器满足使用强度要求。通过本文分析,可为解决万向联轴器在传递动力过程中出现由共振现象所造成的传动误差等问题提供新的思路。The three-dimensional model of the cross-shaft universal coupling is established by Catia software, and the vibration characteristics of the universal coupling are investigated based on Abaqus finite element analysis method. Through modal analysis, the first six orders of solid frequency and vibra-tion pattern of the universal coupling are obtained, and compared with the rotation frequency of the motor in stable operation, it is found that the universal coupling does not have resonance phe-nomenon. Through the static analysis, the maximum stress value and the maximum displacement value of the cross shaft type universal coupling and the cross shaft and fork head are obtained. By calculating the permissible stress value of the cross shaft and fork head and comparing it with the maximum stress value, the universal coupling meets the use of strength requirements. Through the analysis of this paper, it can provide new ideas for solving the problem of transmission error caused by resonance phenomenon in the process of transmitting power of universal coupling.
