A model of a one-dimensional unfolded solar wing was built, and its calculations were performed through finite element analysis (FEA) using MSC software. The actual fundamental frequency of the solar wing was 74.3 Hz, while the comparison between the simulation and the vibration test results was 1.6%. The effects of thickness on the fundamental frequency were investigated. Finally, the substrate was flexible for rigid-flexible coupling and within safe margins for locking impacts and stresses. The locking time of the solar wing was obtained at 1.5 s through multibody dynamics, and the strength and reliability of the hinge locking pin were verified. This study provides ideas and assistance for the design of solar wing structures and mechanisms.

摘要

A model of a one-dimensional unfolded solar wing was built, and its calculations were performed through finite element analysis (FEA) using MSC software. The actual fundamental frequency of the solar wing was 74.3 Hz, while the comparison between the simulation and the vibration test results was 1.6%. The effects of thickness on the fundamental frequency were investigated. Finally, the substrate was flexible for rigid-flexible coupling and within safe margins for locking impacts and stresses. The locking time of the solar wing was obtained at 1.5 s through multibody dynamics, and the strength and reliability of the hinge locking pin were verified. This study provides ideas and assistance for the design of solar wing structures and mechanisms.
