摘要/Abstract

摘要： 针对挂飞情况下,弹架间隙导致的机载外挂系统振动非线性问题,建立了含间隙外挂系统动力学模型。针对简化弹架系统模型,采用有限元方法,取多组弹架间隙值,对外挂振动响应进行了计算。分析了现行外挂在工作频段内,间隙对其振动响应影响的趋势。结果表明:低频段振动响应峰值频率成分复杂,且响应随间隙变大有先减小后变大的趋势;各间隙条件下,中频段响应峰值差距不大;高频段响应随间隙变大而减小。

Abstract: In hanging flight Environment,the nonlinear vibration of aircraft stores is induced by the clearances between the missiles and launchers.Aiming at above problem,the dynamic model of a aircraft store is established.The influence on vibration of the clearance between the missile and launcher is studied theoretically.The vibration responses of various clearances are simulated respectively.The influence trend on vibration response of variation clearance is obtained.The simulation results show that the peak frequency components of the vibration response in the low frequency band are complex,and the vibration response decreases initially and then increases along with the clearance increasing.The peak values of vibration response for various clearances have no distinct difference in mid-frequency band.In higher frequency band, the response decreases along with the clearance increasing.

Key words: aircraft stores, clearances between the missiles and launchers, nonlinear, finite element method, vibration response
