Title Research on Vibration Control Strategies of Tanks
Abstract
To reduce body vibration and improve the accuracy of artillery fire during the vehicles travel, decreasing vibration of tanks is necessary. In this paper, a 1/2 tank dynamic model with 5 degrees of freedom is built. The natural frequency characteristics of the suspension model and the dynamic response to the external excitation are analyzed. Skyhook semi-active control strategy and the linear quadratic optimal active control strategy are studied and compared to explore more effective control strategies. The results show that the two control strategies can effectively reduce the tank vibration, but the advantages of these two methods are different: skyhook is more effective to control vibration of the mass center stroke and the wheel stroke, while the linear quadratic optimal control is more efficient to the mass center acceleration.
