【摘要】 阐述了利用ANSYS参数化设计语言进行大型船用斜齿轮参数化建模及映射分网的方法和具体的实现过程.通过循环加载预定义的主从齿轮转角表数组的方法进行啮合周期内斜齿轮的接触非线性求解计算,表明在大型船用斜齿轮啮合过程中,最大接触应力和齿根最大弯曲应力同时存在突变,但前者没有后者突变明显.啮入时,接触应力和弯曲应力最大;啮合过程中,各数值的变化相对稳定.更多还原

【Abstract】 By ANSYS parametric design language,parameter modeling and mapped meshing of large scale marine helical gears are carried out.Nonlinear solution in a mesh period of helical gears is obtained by circularly loading a predefined corner table array of gear and pinion.The result shows that the maximal contact pressure and the maximal tooth root stress are sudden changed at the same time in meshing process,and the former is not obvious than the later.When helical gears shortly enter into mesh,contact pressure and tooth root stress value are maximal,but in middle meshing process,the change of above two values is relatively stable.更多还原
