Abstract

The invention relates to a test platform and a measurement method for simulating the adhesive movement of flexible surfaces under microgravity, belonging to the field of robots. The test contact reverse side of the flexible surface (11) of the system is uniformly pasted with resistance strain gauges (9) distributed in an array. The bending of the flexible surface (11) will cause the resistance change of the resistance strain gauge (9), and the resistance change value of the resistance strain gauge (9) is collected through the sensor data acquisition system to indirectly measure the bending curvature of the flexible surface (11), combined with the material flexible surface (11 ) modulus of elasticity to indirectly measure the bending moment and force of the flexible surface (11), through the determined distribution position of the resistance strain gauge (9) on the flexible surface (11), the bending moment of the flexible surface (11) can be obtained everywhere moment and force values. The invention has the advantages of simple structure, clear motion principle and convenient motion realization.

Description

technical field [0001] The invention belongs to the application field of robot technology, and in particular relates to a test platform and a measurement method for simulating the adhesion motion of a flexible surface under microgravity. Background technique [0002] Since the Soviet Union launched the first artificial satellite in 1956, human life has benefited more and more from the development of aerospace technology. Aerospace technology has profoundly changed human life, represents the country's scientific and technological strength and comprehensive national strength, is related to national economic interests and national defense security, and has also affected the space security concept of countries around the world. Frontier fields of aerospace technology include on-orbit service, deep space exploration, etc., in which on-orbit service refers to the space operation of spacecraft fault repair, life extension, and task performance improvement through the cooperation of...
