Abstract

The finite element model of the high-torsion flexible coupling is mainly built by finite element analysis software.The static strength analysis and modal analysis of this finite element model is also used in finite element analysis software

the stress and displacement results of the flexible coupling in rated torque are obtained.The former three order modal shape of the flexible coupling and its corresponding frequencies are given.Meanwhile the static radial and torsional rigidity of the flexible coupling are calculated under different radial force and torque load in the rated operating torque.Finally

the corresponding stress are calculated under different speed rotating centrifugal force based on the centrifugal stress analysis methods of the limit speed

and then obtain the critical speed（limit rotational speed） of the flexible coupling.The research shows that the static characteristic method based on finite element method of high-torsion flexible coupling can fairly simulate the static characteristics of flexible coupling accurately to lay the foundation for the design and analysis of flexible coupling.
