Abstract | 用于天文望远镜镜面位置控制的微位移促动器,该微位移促动器一端与支撑镜面相连,另一端与望远镜的机架相连,与支撑镜面的连接点及与望远镜机架的连接点,该两点的连接线构成本微位移促动器的输出轴,特征是微位移促动器由一个弹性结构体及一个主动中心轴组成;弹性结构体是由弹性材料构成的多边形;主动中心轴与微位移促动器的输出轴垂直设置,主动中心轴的基部与端部分别与多边形的两个边或者两个角固定连接。本发明结构简单,连接刚度高,采用多组协同工作,可有效增加镜面与机架间的连接刚度,且不会出现过约束或虚约束现象。在实现位置调整时镜面位移连续,不会出现间隙或空回现象。本发明位移输出精度可达到1微米以下。并可在其它领域应用。 |
Other Abstract | Provided is a micromovement actuator used for controlling the mirror surface position of an astronomical telescope. One end of the micromovement actuator is in connection with a support mirror surface, and the other end is in connection with the frame of the telescope, wherein the connection point with the support mirror surface and the connection point with the frame of the telescope are connected to form a connection line, and the connection line forms the output shaft of the micromovement actuator. The micromovement actuator is characterized by comprising an elastic structure body and an active central shaft; the elastic structure body is a polygon composed of elastic materials; the active central shaft is vertical with the output shaft of the micromovement actuator, and the base and the end of the active central shaft are respectively in fixed connection with two sides or two angles of the polygon. The micromovement actuator has the characteristics of simple structure and high connection rigidity, employs a multi-set cooperative work mode, and can effectively enhance the coupling stiffness between the mirror surface and the frame, and avoid overconstraint or passive constraint; meanwhile, the micromovement actuator can realize continuous mirror surface movement in adjusting a position, and avoid gaps or backlash; besides, the movement output precision can be under one micrometer. The micromovement actuator can be applied to other fields. |
