The rocket launchers vibration test

In the process of launching, due to the influence of the inherent dynamic characters, the interaction of tubes and other factors, it will make the rocket launchers occur vibrations. moreover the vibrations will cause the rocket to deviate from the axial line of the directional device, produce an initial disturbance, and finally bring the rocket a bigger dispersion error So that the article designs the rocket launchers vibration test system including turbulent vibration devices, force sensors, charge magnifier, data collection system, mode analysis system, microcomputer, rockets launcher, accelerator sensor, and printer and then conducts the detailedly analysis of the rocket launchers vibration test from two aspects about the rocket launchers dynamic characters test and launchers vibration test. According to the result of the rocket launchers vibration test, in the guiding phase, the impact of the rocket to the directional tube is evident and the general movement trend of the directional tube is downward; As soon as the semi-restriction phase ends, the directional tube turns around. This illuminates that the influence of the rocket to the directional tube cannot be ignored while taking into account the impact of vibration of the directional tube to the rocket initial disturbances.
