Characteristics Analysis of New Type Aircraft-Arresting System

Working pr inciple of a new type aircsaft-arresting system is described. The mathematic model of the system is given, by which it is made clear that the system is a complex nonlinear autonomy system of second-order andit moves fr eely after initial driving. The existence and the uniqueness of the solution of the differential equation, andt hat the system is asymptotically stable in a big scope are pr oved. Control and motion char acteristics of the systemare analyzed, and the control function of the needle valve throttling area and the cam curve law as manipulated variables is elaborated. The system is a closed2loop process control system. I n simulation, t he dynamic process of arresting and whether the cr iter ia ar e meet ar e shown.
