Abstract
The invention relates to a flexible primary mirror supporting device. The primary mirror comprises two supporting plates, and a plurality of supporting rods arranged between the two supporting plates, wherein each supporting rod comprises a middle rod, two connecting rods arranged at two end parts of the middle rod, and flexible transitional components arranged between the connecting rods and the middle rod; each flexible transitional component comprises a transitional block, an end part connecting plate and a middle connecting plate; the end part connecting plate and the middle connecting plate are parallel to the axial line of the middle rod and are perpendicular to each other; the other ends of two connecting rods are fixedly connected with the corresponding supporting plates; two L-shaped through slots are formed between the transitional block and the end part connecting plate and the connecting rod; two L-shaped through slots are formed between the transitional block and the middle connecting plate and the middle rod; L-shaped through slots are filled with elastic damping cushions. The technical problem that the primary mirror supporting device cannot isolate the influence of external environment and an installing base on a primary mirror is solved; and through the flexible transitional components, the influence of the structural deformation of the installing base and a heat flow on the primary mirror can be effectively isolated.
Description
Technical field
The invention belongs to space exploration, astronomical sight technical field, relate in particular to a kind of primary mirror flexible supporting device.
Background technology
In technical fields such as space exploration, astronomical sights, be the implementation space long-range target acquisition, the exploration of the universe secret, the bore that needs to increase photoelectric detection equipment improves the resolution and the many target energy of mobile phone wind of system, thereby more is prone to find and recognition objective.Heavy caliber primary mirror in these optoelectronic devices is the key component of entire equipment, and it not only receives the influence of external environment but also basic effect is installed, and primary mirror surface types distortion that these effects produce will cause the optical quality of entire equipment to descend.
The primary mirror bracing or strutting arrangement is to be used for that primary mirror is installed in primary mirror the basis is installed, and the primary mirror bracing or strutting arrangement also is vital.Though existing primary mirror bracing or strutting arrangement can satisfy the requirement of support accuracy; But can't isolate for the environment in the external world and the influence on installation basis; Malformation and hot-fluid that the basis is installed do not have and can be delivered on the primary mirror through the primary mirror bracing or strutting arrangement, and primary mirror is impacted.
Summary of the invention
Can't isolate extraneous environment and the influence of basis to primary mirror is installed in order to solve existing primary mirror bracing or strutting arrangement, the present invention provides a kind of primary mirror flexible supporting device.
Technical solution of the present invention:
A kind of primary mirror flexible supporting device, its special character is: comprises two back up pads that laterally arrange and is arranged on a plurality of support bars between two back up pads,
Said support bar comprises intermediate bar, be separately positioned on two connecting links between intermediate bar both ends and the corresponding back up pad, be separately positioned on the flexible transition part between connecting link and the intermediate bar;
Said flexible transition part comprises transition block, end web joint and middle connecting plate; Said end web joint and intermediate bar parallel axes, one of which end and connecting link are connected, and its other end and transition block are connected; Said middle connecting plate and intermediate bar parallel axes, one of which end and intermediate bar are connected, and its other end and transition block are connected; Said end web joint is vertical each other with middle connecting plate; The other end of said two connecting links all is connected with corresponding back up pad;
