摘要：To improve tooth pair meshing quality,we propose a method for
   determining the parameters for gear shape modification,which takes the
   housing stiffness into consideration.We establish the simplification
   algorithm for calculating gear shaft bending and torsional stiffness so
   as to determine the initial values of parameters of the longitudinal
   gear shape modification.We use the ANSYS to establish the finite element
   model for analyzing the contact of gears with a shaft.Using the finite
   element model,we simulate the gear meshing stiffness and determine the
   initial values of the parameters of involute modification and
   longitudinal modification without considering housing stiffness.Finally
   we propose our simplification algorithm for extracting the housing
   stiffness matrix,which is then coupled with the gear shaft,thus
   optimizing the gear shape modification parameters coupled with housing
   stiffness.The simulation results show that our method can greatly
   improve the load distribution on tooth surface,indicating that our
   method is effective.
