直齿圆柱齿轮的参数化建模与模态分析

Based on the theories of gear design in the machine parts,this paper adopts finite the Knowledge Module of 3D design software of CATIA to get the parameterized model of standard involute straight toothed spur gear,and describes this process details.And import the model into the finite element analysis software of ANSYS for modal calculation and analysis.The creation and analysis of Gear parameterized model reflects the CAD/CAE integration of design ideas fully. Practical application shows that just update the parameters to generate a new gear model, which improve model building and analysis of gear efficiency, this is conducive to carrying out follow-up work and produce good results in practical application.
