摘　　要：本文以云南驰宏锌锗股份有限公司会泽冶炼分公司智能剥锌机为研究对象,基于界面及界面力学理论,对剥离过程锌-铝结合界面端模型进行分析,建立了结合界面端的数学特征方程,对结合界面端应力奇异性进行深入研究。通过计算分析,获得了在不同材料结合角度下锌-铝结合界面端的应力奇异性指数的变化规律,结果表明:在锌片剥离过程中,锌-铝结合角度越大,界面端的应力性奇异指数会越大,锌-铝界面在承受同样大小的剥离力时,黏结界面更容易发生剥离。该研究为锌-铝结合层结构的力学建模分析,研究其内部裂纹的产生与拓展奠定了理论基础,具有重要的研究意义。In this paper,the intelligent Zn stripping machine of Huize Smelter of Chihong Zn&Ge Co.,Ltd.is taken as the research object.Based on the theory of interface and interface mechanics,the model of Zn aluminum bonding interface end in stripping process is analyzed,the mathematical characteristic equation of bonding interface end is established,and the stress singularity of bonding interface end is deeply studied.Through the calculation and analysis,the change law of stress singularity index at the end of Zn aluminum bonding interface under different material bonding angles is obtained.The results show that the larger the bonding angle is,the larger the stress singularity index is,and the easier the bonding interface is to peel when the interface bears the same peeling force.This research has laid a theoretical foundation for the mechanical modeling analysis of Zn aluminum bonding layer structure and the study of its internal crack generation and expansion,and has important research significance.
