Abstract

The invention relates to an orthogonal configuration six-degree-of-freedom vibration simulation system and method for a fully vertical actuator, comprising an upper platform assembly, eight actuator branches, a lower platform and a real-time control hardware system; an upper platform assembly and a lower platform The platforms are connected by eight actuator branches in an orthogonal configuration of a fully vertical actuator; each actuator branch is composed of a moving magnetic motor actuator, a hinge assembly and other adapters; The real-time control hardware system obtains the six-degree-of-freedom acceleration signal of the upper platform component collected by the sensor through A / D sampling, and then solves the control signal; the control signal is output to the power amplifier through D / A to drive the actuator to move, and the actuator The driving force is transmitted to the upper platform assembly to produce the desired vibration effect. The invention provides multi-degree-of-freedom vibration excitation in complex environments such as spaceborne, missile-borne, airborne, shipborne or vehicle-borne, and is used to test its stability level and control accuracy in complex vibration environments, or to perform functional performance testing and calibration. .
