| 摘 要： | 内螺纹管滚珠旋压三维有限元模拟中,铜管的网格划分和滚珠加载方式是模拟的关键问题。通过建立简化的六分之一旋转对称模型和采用网格局部重划分技术,成功地模拟和再现内螺纹管滚珠旋压成形过程。对模拟结果的对称面变形的情况分析论证了模型简化的合理性和正确性。对模拟的应变分布和速度分布分析说明,齿成形的多道次局部成形规律。从计算的模具载荷变化情况分析了模具的使用寿命。

| Abstract: | The mesh of copper tubes and loading ways of the balls are the key problems during three dimensional FE simulation of ball spinning of inner grooved tubes.Successfully simulated and replayed the complicated ball spinning of inner grooved tubes through the establishment of simplified sixth rotational symmetrical FE model and the adapting of local remeshing techniques.The analysis of simulated result of the deformation of symmetrical plane proved that the simplified model is reasonable and feasible.The analysis of the distributions of simulated strain and velocity shows that the fins are multi-step local deformed.Finally,the life of dies has been analyzed by the changes of calculated load of the dies. |
