Spacecraft vertical passive separation test equipment

Abstract

The invention discloses spacecraft vertical passive separation test equipment comprising a test rack, a test hanger, a connecting rope, pulley assemblies, a buffering and locking mechanism, a weighting mechanism and a tensile force sensor. The test rack is fixed to the ground through bolts; the pulley assemblies are fixed on transverse beams of the test rack; the connecting rope is connected to the tensile force sensor in series, one end is connected to the test hanger, the other end is connected to the weighting mechanism, and the connecting rope spans on the pulley assemblies and penetrates the buffering and locking mechanism. Compared with the prior art, the spacecraft vertical passive separation test equipment has the advantages that the large-scale spacecraft vertical passive zero-gravity separation test requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of spacecraft ground tests. Specifically, the invention relates to a large-scale spacecraft passive separation test equipment to meet the vertical separation test requirements of large-scale spacecraft under simulated zero-gravity conditions on the ground. Background technique [0002] The separation test methods of spacecraft at home and abroad are mainly divided into two types: free fall type and horizontal separation type. Among them, such as figure 1 Shown is a spacecraft free-fall separation system. Before the test, the spacecraft and the adapter are hoisted as a whole, and the pyrotechnics (explosive bolts) are separated to detonate, and the adapter and the spacecraft are separated and then fall freely, mainly including the crane 1, the spreader 2, the spacecraft 3, the belt assembly 4, and the adapter 5 , Sponge pad6. [0003] Such as figure 2 As shown, it is a horizontal separation system of a s...

AI Technical Summary

Problems solved by technology

[0004] The current separation test equipment has the following defects: 1) Some spacecraft cannot be hoisted in a horizontal state as a whole, because they lack corresponding lifting points, and it is impossible to hoist them in a horizontal state. If L-shaped brackets, process rings, etc. are used The equipment greatly increases the quality of the test piece, which seriously distorts the parameters such as separation speed; 2) The safety of the test piece: the spacecraft are real products. If the free fall method is used, the recovery of the cabin body is very difficult, and sponges cannot be used for recovery. , nor can it be recycled with a spreader; 3) The effectiveness of the test: the exact separation speed cannot be obtained, and it cannot meet the test requirements
