Abstract: Starting with founding the dynamic modal of gear system, the sensitivity analysis method of eigenvalues of gear system is researched by means of the matrix perturbation theory, and its concrete application in design for reducing vibration of gear system is discusssed by a calculation example. Some results with guiding value are obtained. This analysis method lays a foundation for carrying out the dynamic optimum design of gear system.
