Vibration test system and test method for full missile vibration in rotating state of rotating missile

Abstract

The invention provides a vibration test system and test method for full-missile vibration in a rotating state of a rotating missile, and relates to the technical field of missile mechanical environment tests, the vibration test system comprises a vibration device, a fixing device and a rotating device, the fixing device fixes the rotating missile on the vibration device, and the tail end of the rotating missile is connected with the rotating device; the rotating missile achieves application of vibration excitation through the vibration device, achieves balance of missile gravity through the fixing device and achieves application of rotating motion through the rotating device. According to the invention, the vibration dynamics environment experienced by the rotating missile in the flight process can be simulated more truly, and the reliability and vibration environment adaptability of the rotating missile can be fully examined. A non-contact laser sensor is adopted, measurement and control of vibration of the whole missile in the rotating state of the missile are achieved, and the problem that a traditional sensor cannot measure vibration under rotating motion is solved.

Description

technical field [0001] The invention relates to the technical field of missile mechanics environmental test, in particular to a vibration test system and a test method for full missile vibration under the rotating state of a rotating missile. Background technique [0002] As a kind of missile suitable for short-range, low altitude and fast response, the rotating missile has the advantages of simple structure, flexible operation and low cost. It is often used in terminal defense systems. Compared with ordinary missiles, the biggest feature of rotating missiles is that The projectile performs periodic rotational motion, and the frequency is generally between 10 and 20 Hz, so the aerodynamic force generated by the air rudder also performs periodic motion. In the case of only one pair of rudder surfaces, the control force in the 360° direction can also be generated, so the rotating missile can achieve single-channel control through a pair of rudders. However, the rotating state...
