Abstract Reed as a flexible body is prone to coupling resonance, which leads to the decline of operation reliability in reed relay. In this paper, a vibration analysis model of contact spring system is proposed based on beam bending theory, and the natural vibration parameters of contact spring system are calculated numerically. The composite time integration algorithm of Bathe is selected considering the actual vibration conditions, and the natural vibration characteristics of the spring are obtained. At last, the comparison between the vibration test results and the simulation data verifies the accuracy of the solving ability for natural vibration characteristics, which can provide a reference for studying low-voltage electrical appliances of structural optimization.

Key words： Reed relay spring system natural vibration characteristics vibration test
