A Parametric Modeling Approach of Gear and its Precision Analysis
2010
Based on the considerable effect of gear's precise modeling on numerical simulation,and by using APDL-MATLAB parametric modeling approach,a comparatively precise gear model is built by deducing tooth profile curve exactly.Gear root max-bending stress and tooth compliance are simulated and in contrast with the results of experiential formulas,model precision is validated.A conclusion can be drawn: a new thread can be provided by APDL-MATLAB parametric modeling approach in creating an exact and complex curved surface model used in finite element numerical simulation;it can also help raise numerical calculation accuracy.
