Abstract

The invention discloses a platform and a method for testing flexible surface adhesion movement under simulated microgravity and belongs to the field of robots. Resistance strain gauges (9) in array distribution are pasted uniformly on a testing contact reverse side of a flexible surface (11) of a system. Bending of the flexible surface (11) leads to resistance change of the resistance strain gauges (9), resistance change values of the resistance strain gauges (9) are collected through a sensing data collection system to indirectly measure bending curvature of the flexible surface (11), elasticity modulus of the flexible surface (11) of a material is combined to indirectly measuring bending moment and force of the flexible surface (11) at the position, and bending moment and force values ofeach position of the flexible surface can be acquired through planar distribution positions of the resistance strain gauges (9) on the flexible surface (11). The platform is simple in structure, clear in movement principle and convenient for movement realization.

Description

Technical field [0001] The invention belongs to the application field of robot technology, and specifically relates to a test platform and a measurement method for simulating the adhesion movement of a flexible surface under microgravity. Background technique [0002] Since the Soviet Union launched its first artificial satellite in 1956, human life has increasingly benefited from the development of space technology. Aerospace technology has profoundly changed the lives of human beings, representing national scientific and technological strength and comprehensive national strength. At the same time, it is related to national economic interests and national defense security, and it also affects the concept of space security of all countries in the world. The frontier areas of aerospace technology include on-orbit services, deep space exploration, etc., among which on-orbit services refer to the completion of space operations for spacecraft fault repair, life extension, and mission...
