The rocker shaft of automobile steering gear usually adopts non-circular tooth fan rack pair to re-alize non-uniform transmission in the steering process,and its design and manufacture mostly adopt the method of experience and trial and error,which makes the product development cycle long and the efficien-cy low.In view of the demand of enterprises for the design and strength analysis and verification of non-cir-cular toothed fan rack pair of rocker shaft of automobile steering gear,especially the instantaneous state of stress and strain during dynamic meshing,this paper designs a dynamic meshing simulation software of non-circular toothed fan rack pair of rocker shaft based on ANSYS ACT plug-in to complete three-dimensional modeling and simulation analysis.The simulation software consists of three parts:creating a solution pro-ject,three-dimensional parametric modeling and finite element simulation parameterization,which can real-ize the parameterization and modularization of the whole process from design to three-dimensional model-ing to finite element analysis of non-circular toothed sector rack pair of rocker shaft.Compared with tradi-tional design and analysis methods,3D modeling and finite element analysis are integrated into Workbench for dynamic meshing simulation analysis,which greatly improves the design and analysis efficiency of non-circular toothed sector rack pair of automobile rocker shaft.
