摘要
针对大尺寸叶片成形后回弹现象严重的问题,采用DYNAFORM软件模拟叶片成形及回弹过程。得到叶片成形后的成形极限图、厚度变化图等,分析了大尺寸叶片成形所存在的问题,计算其回弹量,为模具设计提供参考依据。
In view of springback problem of the large-sized blades after formation,the study uses DY-NAFORM software to simulate the forming and springback process. With the data about forming limit diagram, thickness variation diagram,the paper analyses the problems of large-sized blades forming and calculates the amount of springback. Hopefully,the study can provide a reference for the actual mold design.
