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 active following of an air floating ball socket, wherein a platform cabin and a load cabin are connected through a magneticlevitation mechanism; an air floating ball bearing assembly of the platform cabin and an air floating ball bearing assembly of the load cabin are arranged in the same sphere center, so that the Rx, Ryand Rz degree-of-freedom co-center movements of the platform cabin and load cabin are achieved; a plane thrust air floating bearing of the platform cabin and a plane thrust air floating bearing of the load cabin are arranged to achieve X and Y degree-of-freedom movements of the platform cabin and load cabin. Through the active control of an electric cylinder arranged on a platform cabin support rod on the platform cabin, the rotation movement of the platform cabin air floating ball socket, actively following the platform cabin air floating ball socket, is achieved, according to the invention,the swing angle is large, the bearing capacity is high, the vertical bearing capacity of the platform cabin air floating ball bearing assembly is obviously increased, the air floating size of the platform cabin air floating ball bearing assembly is reduced, the installing and debugging difficulty and the processing difficulty are obviously reduced.

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 t
