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.
