摘要
本文运用上限单元技术(UBET),引入非完全轴对称单元,模拟了非完全轴对称零件——渐开线齿外花键的成形过程,推导出了成形过程中的速度场公式,并成功地描述了挤压过程中的变形规律。
By means of analytical methods based on upper bound element technique （UBET）, non-axisymmetric element, simulates the forming process of non-axisymmetric involute teeth spline has been introduced, formula of speed fields been derived and the deformation regularity of steady extrusion on the forming process successly described.
