The present paper deals with the numerical modeling and experimental testing of the clinched joint formed by DX51D + AZ150 and AISI 430 material pairs. The strength of the joint was determined experimentally by the tension and shear tests. The numerical model developed for the analysis was successfully validated with the experimental data. The strength of the joint formed by alternative material pairs such as H340LAD + AZ150 and DX52D + Z275 is investigated numerically. The clinched joints between the tumble endplates and flange bodies were done according to the main findings from the previous steps. The study focuses on the strength of the clinched joint as an alternative to flange connection in the case of using different tumble endplate materials. It is concluded that the clinched joint formed by AISI 430 tumble endplate has the highest strength. In the need for tumble capacity increase without changing the design, it is recommended to use AISI 430 material for tumble endplate and to consider strength values of AISI 430 material for capacity control. On the other hand, in case of using three different tumble endplates for the same die, punch and process conditions, the tumble capacity should be evaluated by considering DX52D + Z275 material which has the lowest strength.

本文研究了由DX51D + AZ150和AISI 430材料对形成的铆接接头的数值模拟和实验测试。接头的强度通过拉伸和剪切试验通过实验确定。为该分析开发的数值模型已通过实验数据成功验证。对由替代材料对（例如H340LAD + AZ150和DX52D + Z275）形成的接头的强度进行了数值研究。根据之前步骤的主要发现，完成了滚筒端板和法兰体之间的铆接。在使用不同的翻滚端板材料的情况下，研究重点在于压接接头的强度，以替代法兰连接。结论是，由AISI 430滚筒端板形成的压接接头具有最高的强度。如果需要在不改变设计的情况下增加滚转容量，建议将AISI 430材料用于滚转端板，并考虑AISI 430材料的强度值以进行容量控制。另一方面，在同一模具，冲头和工艺条件下使用三种不同的滚筒终板的情况下，应通过考虑强度最低的DX52D + Z275材料来评估滚筒的容量。
