Abstract

The invention discloses a micro-nano satellite vector vibration testing method, which comprises the steps of determining a vector vibration test strip parameter and manufacturing a vector vibration test fixture, then conducting a vibration test of a micro-nano satellite, fixedly connecting the manufactured vector vibration test fixture with a horizontal vibration stand table board, regarding the vibration stand table board as a datum reference, making a normal of the upper surface of the fixture extend along a designed vector direction v, connecting the micro-nano satellite to the upper surface of the fixture in a butted manner, and applying preset vector vibration magnitude for conducting a test by utilizing a vibration control system. The micro-nano satellite vector vibration testing method realizes vibration tests of the micro-nano satellite in three directions, improves the micro-nano satellite vibration test technical level, and satisfies the high-efficiency and low-cost development requirements of the micro-nano satellite.

Description

technical field [0001] The invention belongs to the technical field of micro-nano-satellite dynamics tests, and in particular relates to a single vector vibration test method for micro-nano-satellites which is equivalent to conventional vibration tests carried out in three orthogonal directions. Background technique [0002] Micro-nano satellites are a new generation of satellites that have developed rapidly in recent years, and are also one of the important directions for the development of spacecraft technology. They have broad application prospects in the fields of earth observation, communication, new technology verification, and scientific experiments. Technical, economic and military value. Micro-nano satellite refers to a type of satellite with a mass of 100kg-1kg, an open architecture and standard interface specifications, and a large number of innovative design concepts and technological developments such as COTS devices, industrial technology, and miniaturized prod...
