摘要/Abstract

摘要： 电阻单元焊接头综合了熔化焊和机械连接的效果，其力学性能由2种连接方式共同决定，而三维有限元模型是研究铝钢电阻单元焊接头力学性能的有效手段.通过金相试验接头宏观形貌，结合硬度实验和经验公式确定接头各区域材料的力学性能，以此作为模型输入.通过该模型，对试验过程中接头断面的几何形貌演化规律以及应力分布特征进行了分析，并结合试验结果研究了接头的失效模式，为揭示接头失效机理提供了借鉴.

Abstract: The mechanical properties of resistance element welding (REW) joints are decided by both effects of fusion welding and mechanical joining. The mechanical properties of REW for aluminum alloy to steel could be effectively studied by three-dimensional finite-element (FE) models. The modeling input consists of cross-section profile of joint observed by metallography, and stress-strain parameters of regional materials obtained by hardness test and empirical formula. Based on this new modeling method, the geometrical evolution and stress distribution during the mechanical testing of REW joints are studied systematically. Via comparing with parallel experimental results, the failure mode of REW joints is analyzed, which provides useful reference to understand the failure mechanism of REW joints.

Key words: resistance element welding, dissimilar material joining, mechanical properties, finite-element model, lap-shear performance, coach-peel performance
