An electromagnetic damping vibration control device for spaceborne equipment

Abstract

The invention relates to an electromagnetic damping type vibration controlling apparatus of spaceborne equipment. The apparatus is composed of a spaceborne equipment mounting interface, a movable connecting rod, a non-magnetic insulation shell, an elastic element group, a compression bolt, a permanent magnet group, coil groups, a satellite platform mounting interface and an electromagnetic enhancement circuit. The top of the movable connecting rod passes through a central hole formed in the upper surface of the non-magnetic insulation shell and is connected with the spaceborne equipment mounting interface. The permanent magnet group is installed on the movable connecting rod; and the compression bolt is installed on the upper surface of the permanent magnet group. One part of the elastic element group is arranged between the non-magnetic insulation shell and the permanent magnet group and the other part is arranged between the upper surface of the satellite platform mounting interface and the lower surface of the movable connecting rod. The non-magnetic insulation shell is installed on the satellite platform mounting interface; and the coil groups are arranged in grooves formed in outer walls of the two sides of the non-magnetic insulation shell. With the apparatus, the spaceborne equipment can stand the tests of various dynamic loads at the launching stage and can operate normally on the track.

Description

technical field [0001] The invention relates to an electromagnetically enhanced damping type vibration control device for spaceborne equipment. An electromagnetically enhanced damping type vibration control device for space-borne equipment designed by the invention provides effective protection measures for vibration control for space-borne equipment, and belongs to the technical field of reliability design of space-borne equipment. Background technique [0002] With the rapid development of communication technology, the demand for space-borne space equipment, such as large antennas, solar panels, and space-borne cameras, is also increasing. Such structures are generally characterized by light weight, flexibility, and large size. When antennas, solar panels, etc. are coupled with the satellite platform, it will seriously affect the accuracy of the satellite's operation and the stability of the attitude, and the spaceborne equipment will be damaged in a very short period of t...

Problems solved by technology

However, there are active and passive vibration control devices commonly used at present. Among them, active vibration suppression devices often have complex structures, poor control loop stability, low structural rigidity, and cannot absorb impact energy to ensure the use accuracy of spaceborne equipment; while passive vibration suppression devices The device is often bulky in structure, with limited damping effect and slow control response. When there is a dynamic load, its elastic elements are prone to failure and slow response, which affects the normal operation of spaceborne equipment.
