Abstract

Hit-to-kill interceptors and other thruster-controlled missiles demand flight motion simulators having sufficiently accurate high frequency dynamic performance to simulate flexible body behavior. A new servoactuator design is described that uses a piezoelectric element to control a novel open-center hydraulic valve. Detailed nonlinear dynamic models are presented for the valve servoamplifier, piezo element, orifice flow, and hydraulic supply decoupling. These are combined with the structural model of a single actuator system. The resulting system model indicates that several such actuators used in combination would provide accurate simulation of missile body vibration signatures up to 1 kHz or beyond.
