【Abstract】 For relay used in aircraft, the item of vibration determines the product’s performance and reliability, spring system is the important component of electromagnetic relay in aircraft. This paper analyzed spring system structure, established its mathematic model for vibration analysis. Based on the analytic theory of vibration mechanic, and the analytical expressions of vibration response of spring system are given. Taken the spring system of some type electromagnetic relay in aircraft as an example, calculated and analyzed the vibration character, draw some instructive conclusion which benefits the design of relay used in aircraft.更多还原
