摘要：

传统渐进成形仿真的时间长，难以有效指导实际工艺开发。基于国产自主研发的AI-FORM软件平台，开发了虚拟多工具算法，实现了渐进成形的快速仿真。通过进行方锥典型件的建模-轨迹设计-模拟-优化一体化仿真流程，对比了单工具和多工具仿真结果的轮廓精度、厚度差异及仿真时间差异，从而验证了虚拟多工具算法的高效性和可靠性。结合实际生产需要，将虚拟多工具算法应用于马鞍形连接件渐进成形工艺仿真中，通过特征分区以及曲线识别优化加工轨迹，对比实际试验件和仿真结果的截面轮廓及特征区厚度，证明了轨迹优化设计的合理性及必要性，并进一步验证了虚拟多工具算法预测实际零件成形的准确性。

Traditional simulation of incremental forming takes a long time, which is difficult to effectively guide the actual process development. Therefore, based on software platform AI-FORM independently developed in China, a virtual multi-tool algorithm was developed to realize the rapid simulation of incremental forming. Then, by carrying out the integrated simulation process of modeling-path design-simulation-optimization for typical pyramid part, the profile accuracy, thickness difference and simulation time difference between single-tool and multi-tool simulation results were compared, and the efficiency and reliability of the virtual multi-tool algorithm were verified. Furthermore, combined with the actual production requirements, the virtual multi-tool algorithm was applied to the simulation of the incremental forming process for saddle-shaped connector, and the machining path was optimized through feature partition and curve recognition. Finally, the rationality and necessity of the path optimization design were proved by comparing cross-sectional profile and feature area thickness between the actual test part and the simulation results, and the accuracy of the virtual multi-tool algorithm in predicting the forming of actual part was further verified.
