Three Dimensional Contact Finite Element Pre processing Technology for Large Width Helical Gears Based on Mixed Coordinate[J]. 1997, (2). DOI: 10.16578/j.issn.1004.2539.1997.02.003.
The existent automatic generation method for 3 D contact finite element analyzing mesh of helical tooth proves to be unsuitable for large width helical gears
and has the limitation of the analyzing model being established only at pitch point.In this paper
concerning at large width helical gears
a mixed coordinate is adopted to built up the automatic finite element mesh generation algorithm for tooth meshing at various positions
and a modular
structural
parametric pre processing program is developed.Only inputting basic parameters of gears
all data for 3 D contact finite element analyzing of helical tooth canbe obtained.The program presented can be used conveniently
and is suitable for application in engineering design.
