摘要:

应用DEFORM软件对铝合金板料摆碾铆接和传统直压铆接两种工艺过程进行数值模拟,对比分析了摆碾铆接工艺过程中应力应变和行程载荷曲线的变化趋势,并对两种铆接方式分别进行了接头性能测试。分析结果表明,在相同行程下达到相同的成形效果时,摆碾铆接需要的载荷要远小于传统直压铆接需要的载荷;摆碾铆接接头的抗撕裂、抗剥离能力优于直压铆接,但抗剪切能力比直压铆接接头弱。

Abstract:

The finite element simulations of the rolling riveting and the pressing riveting for connecting the aluminum alloy sheets were carried out using the finite element software DEFORM. The stress-strain curve and force-displacement curve of the rolling riveting and pressing riveting were compared. The tensile tests of the lap joints for the two kinds of joining technology were performed. The results show that the loads for the rolling riveting are much lower than those for the traditional pressing riveting to achieve the same forming effect. The ability of tear and peeling for the rolling riveting joint is better than those for the pressing riveting, but the shear capacity of the rolling riveting joint is poorer.

Key words: riveting, rolling riveting, press riveting;numerical simulation
