空天飞行器翼面折展驱动系统设计及仿真OA

The escalating complexity of near-space missions imposes stringent demands for miniaturization and reusabil-ity technologies in folding wing systems of morphing aircraft.The integrated hydrostatic helical oscillating mechanism,distinguished by its high-torque capacity,exceptional reliability,and compact configuration,achieves repeated wing de-ployment/retraction through torque transmission and rotational motion,thereby offering critical insights for developing novel drive methodologies for morphing wing deformation.Investigation of morphing aircraft wing mechanisms estab-lished performance requirements for oscillating drive systems,leading to the development of an AMESim-based model for the hydrostatic repeatable oscillating hydraulic system to analyze output characteristics.The results indicate that the hydraulic swing actuator achieves an output rotation of 100° with an output torque exceeding 500 N·m,meeting the wing folding and deploying requirements for near-space morphing aircraft.This research provides technical support for the application of deformable driving mechanisms in folding wings for near-space vehicles.
