Abstract
本发明公开的柴油低速机喷油嘴热等静压成形工艺设计方法，基于热等静压工艺参数与喷油嘴本体参数之间的响应关系，构建热等静压工艺参数‑喷油嘴本体参数数据库；并能够根据输入的喷油嘴本体参数要求以及工艺结果要求，利用有限元模型对工艺结果进行预测，并在预测结果不符合要求时，通过寻优算法在热等静压工艺参数‑喷油嘴本体参数数据库中进行寻优得到最优热等静压工艺参数，使得能够对不合适或不可靠的热等静压工艺参数进行优化设计，进而能够辅助选取更好、更合适的热等静压参数来实现喷油嘴制造过程的粉体致密度‑形状尺寸控制和性能提升；热等静压工艺参数的智能设置避免了工人操作的主观性，使工艺实施更具科学性，同时也提高了参数设置的效率。
