牙齿冷压过盈装配过程的数值模拟
Numeric Simulation of Tooth Fitting Assembly by Pressing
【摘要】 基于接触面的罚函数算法 ,采用非线性动力分析的直接积分理论对牙齿冷压过盈装配过程进行了计算仿真 ,模拟了孔壁压应力在冷压装配中的变化过程 ;以装配时间作为控制参量 ,比较了不同的装配过程对过盈配合的影响 ;仿真过程考虑了设计变量、摩擦系数和工艺参数的影响 ,因此对牙齿过盈设计、装配有一定的指导意义 .
【Abstract】 Based on penalty function algorithm of contact problem and direct integral algorithm for nonlinear dynamic theory, the pressing assembly of tooth fitting is simulated, showing the variation of press stress on hole wall in assembly process. The affects resulted by two pressing processes different in assembly time are analyzed. Taking design parameters, friction and assembly techniques into accountant, this simulation can be used in practice.
