Abstract: |
According to some mission requirements of the space micro-nano satellite solar wing hinge mechanism, a lightweight miniaturization and high reliability active solar wing hinge mechanism is designed in this paper by employing the space stepper motor, brushless rotary transformer, retarding mechanism, micro switch, repeatable deployment, folding and locking mechanism, which adapts to the space application. The modal parameter analysis of the whole machine is carried out. The engineering prototype test verification is completed. The experimental results show that the mechanism has higher positioning accuracy, larger load capacity and better environmental adaptability, which can provide reference for the development of the active solar wing hinge mechanism of the follow-up space micro-nano satellite. |
