摘要
自冲铆接技术作为新型连接技术,在薄板材料的连接中具有优异的连接性能。其接头质量受连接的可行性和连接参数的影响,而接头质量主要由接头的力学性能来表征,因此接头的质量和力学性能已成为目前自冲铆技术的主要研究方向。随着数值模拟技术的发展,它在自冲铆连接技术上的应用成为一种研究趋势。对近年来自冲铆数值模拟技术的发展进行系统阐述,从自冲铆接头成形质量的数值模拟技术出发,对自冲铆数值模型建立、自冲铆影响因素研究、数值模型优化和数值预测模型4个方面进行说明,综述了材料连接的可行性和连接参数对接头性能的影响,对接头力学性能进行模拟,并对接头力学强度和疲劳寿命进行预测,为自冲铆工艺的研究和发展提供新的方向。
