Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0026] Such as figure 1 As shown, a reduction gear bond graph model optimization method based on a six-degree-of-freedom gear meshing model follows the steps below:

[0027] S1: According to the physical model of the first-stage gear pair, a six-degree-of-freedom meshing dynamics model of the first-stage gear pair is established.

[0028] See figure 1 , under the influence of tooth surface friction factors, each gear will have three degrees of freedom during the meshing process, namely the x direction, y direction and the rotation direction, so the support stiffness and The damping is equivalent to the value in the x and y direction with the combined equivalent value with k px 、k py 、k gx 、k gy and c px 、c py 、c gx 、c gy To represent, mesh stiffness and damping with the combined equivalent value k m and c m express.

[0029] S2: According to the ...

Abstract

The invention discloses a method for optimizing the bonding graph model of a reducer based on a six-degree-of-freedom gear meshing model, which is carried out according to the following steps: S1: establish a six-degree-of-freedom first-stage gear pair meshing dynamics model; S2: establish a six-degree-of-freedom meshing dynamics model The bond graph model of the first-stage gear pair; S3: Deduce the state equation of the bond graph model of the first-stage gear pair; S4: Establish the bond graph model of the reducer; S5: Deduce the bond graph model of the reducer State equation; S6: Perform simulation analysis on the state equation of the reducer bond graph model, and correct the reducer bond graph model. Using the above technical solutions, the bond graph model of the gear pair and the bond graph model of the reducer can accurately analyze the characteristics of the reducer and other gear transmission mechanisms, and provide a theoretical basis for the optimal design of the reducer and other gear transmission systems .

Description

technical field [0001] The invention relates to the technical field of transmission system optimization design, in particular to a method for optimizing a bond graph model of a reducer based on a six-degree-of-freedom gear meshing model. Background technique [0002] In recent years, since the bond graph model can be simulated forward and backward, the system construction and related parameters can be changed flexibly and conveniently, the corresponding mathematical model can be easily written from the bond graph model, and the physical In order to understand the internal connection and energy transfer of the model, some researchers have begun to try to use the bond graph method to model the reducer. [0003] Since the gear is not rigidly supported during the meshing process and there is tooth surface friction when the gear meshes, the gear has movement in the x and y directions, and it is also affected by stiffness and y during the movement in the xx and y directions The e...
