摘要：

Coupled torsional-flexural vibration of a shaft in a spur geared system is investigated. Equation of motion which contains the terms of geometrical eccentricity of gears and mass unbalance are introduced. The coupling between torsional and flexural displacements is considered in the equations which assume that surfaces of tooth of meshed gears are always in contact during the rotation. By solving the equation, it is possible to get natural frequencies, mode shapes, and frequency response of the system. It is usual to ignore the effect of the coupling between torsional and flexural vibrations. But comparing the result with them, some new phenomena were revealed. They are: (1) shifts of the critical speeds, (2) transformations of the mode shapes, (3) a forced vibration which is caused by geometrical eccentricity of a gear.
