Название
(EN) Adaptive under-actuated non-cooperative target space capturing mechanism
(ZH) 一种自适应欠驱动式非合作目标空间捕获机构
Реферат
(EN) The invention discloses an adaptive under-actuated non-cooperative target capturing mechanism. An existing capturing mechanism is poor in adaptation of the size and shape of a target. A nut driving plate and a stretching platform form a helical pair with a first thread and a second thread of a variable pitch screw respectively; the nut driving plate is provided with an armature, and the stretchingplatform is provided with an armature and a travel switch; a mechanical arm driving plate is connected with the nut driving plate through a flexible connecting part; three five-rod type mechanical arm bodies are uniformly distributed in the circumferential direction and connected to the mechanical arm driving plate; a third connecting rod in each five-rod type mechanical arm body can cooperate with a torsional spring to be converted to be an under-actuated mechanism; mechanical arm tail end execution mechanisms are connected to the three five-rod type type mechanical arm bodies; a buffer guide mechanism is located in the center of the circumference where the three five-rod type type mechanical arm bodies are uniformly distributed. Accordingly, a single power source is adopted for achieving unfolding of three mechanical arms, the mechanism has the multi-degree of freedom and can flexibly adapt to target satellite spray pipes with different sizes and shapes.
(ZH) 本发明公开了一种自适应欠驱动式非合作目标空间捕获机构。现有捕获机构对捕获目标的尺寸和形状适应性不强。本发明的螺母驱动板和伸展平台分别与变螺距丝杆的第一螺纹和第二螺纹构成螺旋副;螺母驱动板设有衔铁,伸展平台设有电磁铁和行程开关;机械臂驱动板与螺母驱动板通过柔性连接部件连接;三个五杆式机械臂本体沿周向均布且连接在机械臂驱动板上;五杆式机械臂本体中的第三连杆可与扭簧配合转变为欠驱动机构;三个五杆式机械臂本体上均连接有机械臂末端执行机构;缓冲导向机构位于三个五杆式机械臂本体所均布圆周的中心处。本发明采用单一动力源实现三个机械臂展开,具有多自由度,能灵活适应不同尺寸、形状的目标卫星喷管。
