EXPERIMENTAL RESEARCH ON ITS DYNAMIC RESPONSE AND ACTIVE VIBRATION CONTROL OF FLEXIBLE COMPOSITE MATERIAL BARREL UNDER A MOVING PROJECTILE
The coupling vibration model between a moving projectile and a flexible composite barrel was established. And the individual and coupling effects of its velocity of the moving projectile and its mass on the dynamic response of flexible composite material barrel were researched in detail by the developed experimental platform in this paper. Based on Euler-Bemoulli beam theory and mode theory, the state space model between the controlled voltage and its dynamic response of the flexible composite barrel bonded with piezoelectric sensors and actuators were derived and established. Experimental results showed that compared with its free vibration of the flexible beam, its vibration amplitude reduces off 35% under the same working conditions by using the active vibration control technology. Besides, a suit of real-time measuring-controlling system including hardware and software for active vibration control of flexible smart composite barrel was developed, which would establish further the basis of integrated design and engineering implementation for its active vibration control of the weapon assemblage system.
