Embedded semi-physical simulation system based on active following of air-floating ball socket

Abstract

The invention provides an embedded semi-physical simulation system based on the active following of the air-floating ball socket. The platform cabin and the load cabin are connected by a magnetic levitation mechanism, and the air-floating ball bearing assembly in the platform cabin and the air-floating ball bearing assembly in the load cabin are set at the same spherical center. Realize the Rx, Ry and Rz degrees of freedom of the platform cabin and the load cabin, the common spherical center movement, the platform cabin plane thrust air bearing and the load cabin plane thrust air bearing, realize the X and Y freedom movement of the platform cabin and the load cabin , on the platform cabin, through the active control of the electric cylinder set on the platform cabin support rod, the platform cabin air float ball socket actively follows the platform cabin air float ball’s rotation movement, the present invention has a large swing angle and a high bearing capacity, and at the same time significantly increases The vertical bearing capacity of the air-floating ball bearing assembly in the platform cabin reduces the size of the air-floating ball diameter of the air-floating ball bearing assembly in the platform cabin, and significantly reduces the difficulty of assembly and processing.

Description

technical field [0001] The invention relates to the field of spacecraft physical simulation, in particular to an embedded semi-physical simulation system based on the active following of an air-floating ball socket. Background technique [0002] With the rapid development of science and technology, space-to-earth observation remote sensing tasks are gradually developing towards high spatial resolution and high efficiency, and the high spatial resolution and high efficiency of observation remote sensing mainly depend on the pointing accuracy, stability and agile maneuvering of satellite loads performance. In traditional satellite platforms, flexible accessories such as large solar panels and movable parts such as flywheels, gyroscopes, and drive mechanisms are the main reasons that affect the satellite load attitude pointing accuracy, stability, and agile maneuverability. [0003] In the conventional satellite design, the payload module is fixedly connected with the platform...

Problems solved by technology

However, due to the built-in configuration of the double five-degree-of-freedom air bearing table, the device cannot obtain a large-angle maneuvering test with a swing angle greater than 20 degrees, and the device will cause the air bearing in the external five-degree-of-freedom air bearing to form a Narrow ball ring with air-floating support structure, which leads to extremely difficult processing of large-scale air-floating ball bearings, and poor air-floating working characteristics
