Six-DOF (degree of freedom) air floatation type motion simulator

Abstract

A six-DOF (degree of freedom) air floatation type motion simulator comprises a translation platform and a posture platform. The translation platform comprises a spherical air bearing, an anti-rollover mechanical limiter, a lifting post assembly, a first air pressure line, a first controller, three planar air bearings, a translation platform mounting panel and a translation platform lithium battery. The posture platform comprises a posture platform mounting panel, 2N air cylinders, a second air pressure line, an iGPS, four cold air nozzle groups, an inertial navigation system, a second controller, three flywheels, a mass center adjustment system and a posture platform lithium battery. The translation platform finishes translational motion in its X and Y directions. The posture platform finishes its rotational motion in X, Y and Z directions of a system of proprio-coordinate and its translational motion along an axis Z, thus simulating spatial posture rotational motion and orbital translational motion of an aircraft.

Description

technical field [0001] The invention relates to a six-degree-of-freedom motion simulator for simulating space activities of spacecraft such as satellites based on the principle of air flotation, and belongs to the field of half-physical simulation of space vehicles. Background technique [0002] The six-degree-of-freedom air flotation simulator for space interception is the core component of the evasion maneuver hardware-in-the-loop simulation system. Its core function is to realize the tracking of the evasion level air flotation simulator (attacker) by the EKV according to the control command of the evasion maneuver master control system sports. [0003] In recent years, on the basis of the introduction of foreign advanced air flotation simulation test systems, some key domestic universities and research institutions have conducted research on some performances and uses of air flotation simulation test systems, but they are mainly used in space rendezvous and docking, etc. ...
