Nonlinear Dynamic Characteristics of Supercavitating Vehicle Based on Two-dimensional Bifurcation
摘要
Abstract
Based on two-dimensional bifurcation diagram,the complex dynamic behaviors of supercavitating vehicles were analyzed by using dynamic analysis tools,such as phase track diagram,timedomain simulation diagram,Lyapunov exponent spectrum.The motion of supercavitating vehicle changing with feedback control gain of the tail deflection angle and cavitation numbers was explored,and the conditions and ranges of variable parameters for the stable motion of vehicle were determined.The results show that some rich nonlinear phenomena varying with variable parameters,such as bifurcations,period windows and chaos can be found.Vibrations and shocks can be suppressed effectively by reasonably adjusting the tail deflection angle.The research result has an important guiding significance to the design of the controller of supercavitating vehicle.关键词
