Deform HT software was used to analyze the heat treatment process of hot-dip galvanized aluminum alloy hanging plate by selecting two kinds of hanging plate hardwares,which were commonly used in transmission lines.The theory of multi-field coupling for heat treatment of hardware was introduced.The finite element analysis model of two kinds of hanging plates was established,and the temperature field and stress field change of the heat treatment process were analyzed respectively.The results show that the cooling rate of ball-head hanging plate and bowl-head hanging plate is fast and the overall cooling rate of parts is not balanced.The stress change of the ball-head hanging plate is more intense in the quenching stage,and the stress at the structural joint is greater than that at the center of the hanging plate.In the final stage of the heat treatment process,the stress position of the hanging plate of the bowl head is located at the joint between the top bowl head and the the lower ring.The research results are helpful to find the weak links and weak parts in the heat treatment process of hanging plate fittings,and can provide references for relevant technicians.
