摘　　要：以典型双曲率飞机壁板零件为例,采用Geomagic软件分析其零件特征并设计2条喷丸路径,初步建立喷丸参数与等效温度值的映射关系,通过有限元软件ABAQUS中显式–隐式顺序方法进行"温度场"等效模拟,计算沿既定喷丸路径的成形情况,用Geomagic软件表征其成形误差;并根据其成形误差优化所设计的喷丸路径,得到工件最理想成形效果;最后结合1:1全尺寸试验件喷丸成形试验进行验证。结果表明:该等效模拟法可以正确预测既定喷丸路径下的成形结果并且可以优化喷丸路径,对喷丸成形工艺的路径规划具有重要的指导意义。Taking a typical double curvature aircraft panel part as an example,the 2 kinds of shot peening paths were designed according to part characteristics,which were analyzed by Geomagic software.Next,the initial mapping relationship between shot peening parameters and equivalent temperature was established,and the“temperature field”equivalent simulation was carried out by finite element software ABAQUS with the order of the transient steady-state method.And then,Geomagic software was used to characterize the forming error.According to its forming error,the plan of the path was optimized,and the ideal forming result was obtained.Finally,the forming result was verified by a shot peening test of a 1:1 test piece.The result showed that the equivalent simulation method can predict the forming result of the established shot peening path correctly and optimize the shot peening path,which was of great significance to the path designing of shot peening forming.
