Problems solved by technology

[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. In the low field, high-speed target countermeasure tests have not been carried out on the air-floating platform
[0004] In addition, the translational platform (TP platform) of the current five-degree-of-freedom air-floating motion simulator is realized by a fixed column, and the height cannot be adjusted, which increases the difficulty of docking with other simulators; the attitude control of the attitude platform is realized through the nozzle. The precision is not high, the response speed is slow, and it is not suitable for high-speed sports occasions; the positioning uses a load vision system, which has low precision and complex structure

Embodiment Construction

[0045] The air-floating motion simulator can be used on the ground to simulate the space activities of spacecraft under the condition of microgravity. This is a unique ground-based full-physics simulation method in the process of developing satellites and other spacecraft. The access loop is very important to verify the correctness of the design of the spacecraft control system and to verify the function and performance of the actual control system.

[0046] Such as figure 1 As shown, the five-degree-of-freedom air-floating motion simulator designed by the present invention is divided into a translation platform (TP platform) and an attitude platform (AP platform). Complete the rotation motion along the X, Y, and Z directions of the AP platform body coordinate system (pitch axis, roll axis, yaw axis), and the two platforms are separated by the air film between the spherical air bearings. The invention realizes the simulation of space attitude rotation motion and orbit transla...

Abstract

A 5-DOF air-float motion simulator comprises a translation platform and an attitude platform. The translation platform comprises a ball surface air-float bearing, a rollover-preventing mechanical stop device, an elevating column, a first air pressure pipeline, a first controller, three plane air-float bearings, a translation platform installation panel, and a translation platform lithium battery. The attitude platform comprises an attitude platform installation panel, 2N air bottles, a second air pressure pipeline, an iGPS, four cold air nozzle, an inertial navigation system, a second controller, three fly wheels, a center of mass adjustment system, and an attitude platform lithium battery. The translation platform accomplishes translation movement in the X and Y directions, the attitude platform accomplishes rotation with respect to the pitch axis, roll axis and yaw axis, so that the simulator achieves simulation of spatial attitude rotation and track translation movement of a spacecraft.

Description

technical field [0001] The invention relates to a five-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 five-degree-of-freedom air flotation simulator for space interception is the core component of the evasion maneuver semi-physical 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. High...
