摘　　要：提出一种基于不锈钢板的微通道管辊弯成形制造方法,开展了针对封闭型复杂截面的辊弯成形花形设计;基于ABAQUS软件采用有限元显式算法对微通道管辊弯成形过程进行模拟。通过有限元仿真,分析了辊弯成形过程中板料截面的等效应力和塑性应变,探讨了不锈钢微通道管辊弯成形工艺的可行性。The roll forming method of microchannel tube based on stainless steel sheet is proposed.The roll forming pattern design for closed complex sections is carried out.The finite element explicit algorithm is used to calculate the roll forming process of the microchannel tube.Through the finite element simulation,the equivalent stress and plastic strain of the sheet section in the roll forming process are analyzed.The feasibility of roll forming process for stainless steel microchannel tube is discussed.
