Anti-sway vibration isolating device for reducing micro-vibration of flywheel

Abstract

The invention discloses an anti-sway vibration isolating device for reducing micro-vibration of a flywheel, and belongs to the technical field of aerospace equipment. The anti-sway vibration isolatingdevice is provided with a satellite capsule plate, and the upper portion of the satellite capsule plate is fixedly connected with a mounting bracket provided with the flywheel through the vibration isolating device; the vibration isolating device comprises a gasket, a vibration isolating pad and a shaft sleeve, the gasket is in contact with the upper end of the shaft sleeve, the lower end of theshaft sleeve is in contact with the upper surface of the satellite capsule plate, the exterior of the shaft sleeve is sleeved with the vibration isolating pad for absorbing vibration shock, and the vibration isolating pad and the mounting bracket are in flexible contact; and an anti-sway device comprises a sleeve and an anti-sway bar, the outer wall of the sleeve is fixedly connected with the mounting bracket, the inner wall of the sleeve is arranged outside the anti-sway bar in a sleeving manner, an overlapping area of one end of the anti-sway bar and the sleeve is fixedly connected with an energy sucking sleeve, the energy sucking sleeve is in clearance fit with the sleeve, and the other end of the anti-sway bar is fixedly connected with the satellite capsule plate through bolts. The anti-sway vibration isolating device reduces micro-vibration and swing of the flywheel and is simple in structure and light in weight.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to an anti-sway vibration isolation device for reducing microvibration of a flywheel. Background technique [0002] High-resolution optical satellites have extremely high requirements on micro-vibration. Micro-vibration may cause the optical load to shake, thereby reducing the pointing accuracy and stability of the satellite, resulting in a decline in imaging quality, and even image distortion. Micro-vibration on the satellite It mainly comes from the moving parts on the satellite, among which the flywheel is the main source of micro-vibration. Therefore, how to reduce the influence of the micro-vibration of the flywheel on the optical load is of great significance to improve the satellite resolution and ensure the imaging quality.

Problems solved by technology

[0005] 1. The device contains multiple components, which is highly complex and reduces the reliability of use;

[0006] 2. The unlocking of pyrotechnics requires a strong current, which occupies the power resources of the satellite system. Moreover, the size and weight are relatively large, so it is not suitable for small and micro satellites with small battery capacity and high requirements for size and weight.
