Tool for rapidly testing quality characteristics of batch satellites, and testing method

Abstract

The invention provides a tool for rapidly testing quality characteristics of batch satellites, and a testing method. The tool comprises an outer supporting frame, an inner supporting frame, a shafting1, a shafting 2, a shafting 3, an adapter plate, a positioning block, a horizontal stop block and a vertical stop block, wherein the inner supporting frame is arranged in the outer supporting frame,the inner supporting frame rotates around the shafting 1 and the shafting 2, and the adapter plate rotates around the shafting III; an included angle between the outer supporting frame and the inner supporting frame is 0 degree through matched positioning of the horizontal stop block and the positioning block; the included angle between the inner supporting frame and the outer supporting frame is90 degrees through matched positioning of the vertical stop block and the positioning block; and positioning of the adapter plate is achieved by installing the positioning pin on the adapter plate. The tool is high in test efficiency, simple in structure, small in size, high in test precision, high in universality and safe and reliable in operation, the mass, the mass center and the moment of inertia parameters of a satellite can be measured after the satellite is installed at a time, the test efficiency is greatly improved, and the tool is particularly suitable for batch satellite quality characteristic test requirements.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a tooling and a testing method for rapid quality characteristic testing of mass-produced satellites. Background technique [0002] Traditional quality characteristic testing equipment requires vertical tooling and L-shaped tooling. The satellite first needs to be hoisted to the vertical tooling with a crane to measure the center of mass in the X and Y directions and the moment of inertia of the Z-axis, and then the entire satellite is disassembled and lifted to the L-shaped tooling. Install on the tooling, test the center of mass in the Z direction and the inertia in the X and Y directions. The satellite needs to switch between the two toolings. During the disassembly process, it is not conducive to improving test accuracy, work efficiency and ensuring production safety. This test method is more suitable for the current single satellite or small batch test. When t...

During the disassembly process, it is not conducive to improving test accuracy, work efficiency and ensuring production safety

This test method is more suitable for the current single satellite or small batch test. When the number of satellites reaches the mass production scale, this method will be difficult to match the production capacity
