摘　　要：文中首先提出电磁式防振锤的新型设计思路,分析其工作原理;然后根据动力学理论建立机械部分的振动模型,吸收风振的能量;根据电磁感应原理及电桥理论,将输电线微风振动的机械能转换成了电能,并以热能的形式消耗在电桥的电阻上,由基尔霍夫定律建立一组非线性数学模型。与FKH-5Z机械防振锤比较,电磁防振锤频带响应宽,防振效果好。The new typed designing train of thought on the electromagnetic anti-vibration hammer was firstly put forward; its working principle was analyzed. And then according to the dynamics theory the vibration model of the mechanical part was established for calculating the absorbed energy from wind vibration. On the basis of electromagnetic induction principle and electrical bridge theory, let the mechanical energy of breeze vibration of power transmission line be transformed into the electric energy and to be consumed in the form of thermal energy on the resistance of electrical bridge. A set of nonlinear mathematical model was established by the Kirchhoff law. Compared with the FKH-SZ mechanical anti-vibration hammer the frequency band response of electromagnetic anti-vibration hammer was wider and its anti-vibration effect was good.
