Abstract

The invention discloses microsatellite quality characteristic bidirectional testing equipment. A U-shaped symmetrical inner and outer supporting frame structure is adopted; an inner supporting frame is driven to rotate around a rotating shaft by a speed-reducing mechanism and is easily positioned in vertical and horizontal directions through a positioning mechanism; and the problem of rapid coordinate conversion in a vertical state and a horizontal state through one-time hoisting is solved. The quality characteristic data in two states is tested through one-time hoisting and clamping in the field of microsatellites, the quality characteristic testing time is shortened, the testing efficiency and testing effect are improved, the safety and reliability of the quality characteristic testing are enhanced, and the labor intensity of personnel is greatly lightened. The microsatellite quality characteristic bidirectional testing equipment has a simple structure, is convenient to operate, and can be used for quality characteristic testing of spacecrafts and other miniature equipment.

Description

technical field [0001] The invention relates to a test device for measuring satellite quality characteristics and a method for using the device to test the quality characteristics. Background technique [0002] Through the mass characteristic test, the mass characteristic data of the satellite can be obtained, and these data include: the satellite mass M, in the star coordinate system (the origin is the center of the docking ring, the Z axis is perpendicular to the docking ring surface, points vertically upward to the star, and the X axis is horizontal In any direction, determine the Y-axis according to the right-hand rule, the position of the center of mass (X, Y, Z) in ), and measure the moment of inertia lxx, lyy, lzz. When measuring the center of mass of the satellite, first measure the center of mass of the X-axis and Y-axis in the vertical state of the satellite, and then measure the center of mass of the Z-axis in the horizontal state. The measurement sequence of sa...
