Problems solved by technology

In this way, there must be eccentricity so that the mass of the attachment acts laterally on the suspension device, resulting in friction on the mechanism for deploying the attachment, thus affecting the effectiveness of the test. In severe cases, the attachment may even fall over.
At the same time, considering that the accuracy of the gravity unloading of the unfolding attachment by the air flotation device is difficult to ensure accurately (the air buoyancy force has a nonlinear state), that is, there is a certain impact on the deployment mechanism of the unfolding attachment, especially in the eccentric state of the attachment, it is difficult to guarantee the validity of the test

Abstract

The invention provides an adjustable suspension device for a satellite eccentric unfolding accessory and an application of adjustable suspension device. The device comprises a suspension cross beam, apositioning cross beam, a suspension vertical beam, a suspension rope, and a spring scale. The suspension cross beam is connected with the positioning cross beam. The positioning cross beam is connected with the suspension vertical beam. One end of the suspension rod is bound to the suspension vertical beam and one end is bound to the spring scale. The suspension cross beam is connected with theeccentric unfolding accessory. In the suspension state, the length of the suspension rope is adjusted, so the tensile force of the spring scale is equal to the gravity of the unfolding accessory, so the gravity of the eccentric unfolding accessory is precisely unloaded. According to the invention, friction, overturning and the like caused by eccentricity can be effectively prevented from causing test failures; and it is reliably ensured that ground unfolding test of the satellite unfolding accessory is effectively and smoothly finished.

Description

technical field [0001] The invention relates to an adjustable suspension device for satellite eccentric deployment accessories, belonging to the field of suspension devices for ground deployment experiments of satellite deployable accessories. Background technique [0002] With the development of technology, satellite deployment accessories (such as solar arrays, antenna arrays, etc.) have more and more eccentric characteristics, that is, the center of mass of the deployment accessories cannot be guaranteed to be within the suspension vertical plane of the suspension device and the deployment accessories. In this way, there must be an eccentricity that causes the mass of the attachment to act on the suspension device laterally, resulting in friction on the deployment attachment mechanism, thereby affecting the validity of the test, and even the deployment of the attachment may tip over in severe cases. At the same time, considering that the accuracy of the gravity unloading ...
