摘　　要：对一类小型电磁继电器衔铁──触头簧片结构建立刚体－弹簧－阻尼分段线性力学模型，给出了振动响应的解析式，并以ＪＺＸ－１０Ｍ结构参数编程计算，较全面地研究了继电器在释放（危险）状态下衔铁运动规律，具体探讨了产生抖动的可能性及影响因素。产品振动试验和结构改型实践说明了该工作是可行的。This paper first establishes a multi-segment linear body-spring-damping vibration modeland presents the analytical solutions of the vibrating response,then calculates the responseaccording to structure parameters of JZX-10M relay using a special program RELAY. It in-vestigates the motion law of the armature in detail when the relay is under the release(dan-gerous)state, and further discusses the possibility and effect factors of causing the tremblephenomenon. Vibrating tests and the practice of structure retrofit designs show this work issuitable to the relay.
