本文针对应用上限元法反向模拟叶片成形过程时所遇到的具体问题的处理，提出一系列算法，开发了叶片成形过程的上限元反向模拟系统，并应用该系统分析、确定了合理的叶片预制坯形状
In this paper, a series of algorithms are proposed to deal with the specific problems encountered in the process of reverse simulation of blade forming by the upper bound element method. The upper finite element inverse simulation system of the blade forming process is developed. With the analysis of the system, Blade preform shape
