Dynamic analysis of deployable solar panel

Solar panel is the conversion device that converts the sun energy into electricity, and it is the important part of planetary exploration rover. It provides support to lunar rovers for essential electric power to the normal driving and work. A turnover mechanism of solar panel was proposed, which could effectively track the solar angle, achieve and maintain random angle within its rotational range. Dynamic models of solar panel during deployment stage and forced vibration were built based on Kirchhoff theory and Hamilton theory, in order to analyze the Dynamic characteristics of the solar panel while deploying and vibrating. Driving torque curve of driving torsion bar during deployment stage, natural frequency and mode of vibration of solar panel are obtained, which are verified by virtual simulation in ADAMS and vibration test. At the same time, response characteristic of solar panel was analyzed when it encountered instantaneous impact. Response curves of solar panel with different damping are obtained.
