Orthogonal configuration six-degree-of-freedom vibration simulation system and method of full-vertical actuator

Abstract

The invention relates to an orthogonal configuration six-degree-of-freedom vibration simulation system and method of a full-vertical actuator. The system comprises an upper platform assembly, eight actuator branches, a lower platform and a real-time control hardware system, wherein the upper platform assembly and the lower platform are connected through eight actuator branches in an orthogonal configuration of a full-vertical actuator; each actuator branch is composed of a moving magnet type motor actuator, a hinge assembly and other adapters; the real-time control hardware system obtains a six-degree-of-freedom acceleration signal of the upper platform assembly collected by the sensor through A / D sampling, and calculates a control signal; a control signal is outputted to the power amplifier through the D / A to drive the actuator to move, and the actuating force of the actuator is transmitted to the upper platform assembly to enable the upper platform assembly to generate an expected vibration effect. The system is advantaged in that multi-degree-of-freedom vibration excitation in complex environments such as satellite-borne, missile-borne, airborne, ship-borne or vehicle-mounted environments is provided, and the multi-degree-of-freedom vibration excitation is used for checking the stability level and control precision of the multi-degree-of-freedom vibration excitation in the complex vibration environments or testing and calibrating the functional performance of the multi-degree-of-freedom vibration excitation.
