AI Technical Summary

Technical Problem

Existing ground-based testing equipment cannot adapt to the motion trajectory of multi-step deployable solar arrays, making it difficult to accurately simulate weightlessness throughout the entire process. This results in damage to the substrate due to stress, and the integrity of the test structure cannot be guaranteed.

Method used

The solar array employs a first deployment mechanism and a second deployment mechanism, which respectively utilize a two-dimensional slide bar mechanism and a sliding roller mechanism to achieve multi-step deployment of the solar array. This simulates a weightless state, reduces the compressive load and bending stress on the hinge due to the self-weight of the substrate, and prevents the hinge from deforming and being damaged.

Benefits of technology

It achieved accurate simulation of multi-step deployable solar array ground deployment test, ensuring smooth deployment of the solar array in a weightless state, avoiding damage to the substrate under stress, and ensuring the integrity of the test structure.

Abstract

The present application relates to a kind of multi-step deployment solar wing ground deployment test device, the deployment of the multi-step deployment solar wing includes first step deployment and second step deployment, the first step deployment corresponds the deployment action of primary substrate, and the second step deployment corresponds the deployment action of secondary substrate;The ground deployment test device includes: first deployment mechanism, it is configured to follow primary substrate synchronous motion, in turn, make primary substrate in first step deployment in weightlessness;And second deployment mechanism, it is configured to follow secondary substrate synchronous motion, in turn, make secondary substrate in second step deployment in weightlessness.The present application realizes that multi-step deployment solar wing ground deployment test can be carried out smoothly in the state of simulation in orbit, in turn, avoid substrate stress breakage, guarantee test structure intact.
