The Research And Design Of Spacecraft Solar Wings Dynamic Effects Measurement System

When working in space, Spacecraft mainly depend on the solar cells which are installed on solar wings to provide energy. As the spacecraft energy demand continues to increase, the area of spacecraft solar wings continues to expand. Large-scale solar wings'impact to the spacecraft body has become an important research topic in aerospace technology.In order to implement the spacecraft solar wings dynamic effects measurement system, which is used in ground simulation experiment, this paper focuses on the research of solar wings'ground simulation, drive mechanism shaft offset processing, monitoring and control software design.First, this paper analyzes the disturbance torque conditions when large-scale solar wings operate in space environment, and demonstrate the effectiveness of using the same inertia simulation solar wings. By comparing with the flotation platform program, propose using sensor to eliminate gravity, and design spacecraft solar wings dynamic effects measurement system.In addition, study on drive mechanism shaft offset problem. By the analysis of measurement data and working mechanism, obtain the characteristics of the disturbance. Design a threshold delay start digital IIR filter to supply the demand when driving mechanism start.Finally, based on the above algorithm,monitoring and control software is developed using C + + to support the spacecraft solar wings dynamic effects measurement system. The software is so powerful that provides dynamic data display, drive mechanism control, data analysis and statistics, data storage and output functions, etc.
