Abstract
The invention discloses a DVOR (Doppler Vor) omnidirectional range reflective net antenna damping system. A damping support I is arranged between an upper strut and a lower strut of a reflective net bracket, a damping support II is arranged between a reflective net and an antenna orbit, and the two damping supports are high-damping rubber gaskets with built-in gasket lined steel plates. The system is reasonable in design and convenient to install, and is easy to replace when the rubber is aged after installation; the damping support I is arranged between a steel girder and the orbit, so that contact between meshes and the orbit is radically avoided, and the trample problem during overhauling or construction is solved; the damping supports serving as dampers consume energy inside, thus effectively counteracting the influence of wind load on an orbit antenna under severe weather and reducing the vibration frequency and times of the antenna orbit; the antenna orbit is effectively separated from the reflective net steel girder, thus avoiding resonance caused by the same frequency with the reflective net; and the damping support II prolongs the natural vibration period of the structure and reduces the vibration frequency of the structure without influencing the structural strength.
Description
Technical field
The present invention relates in Civil Aviation System and receive and reflect the antenna assembly of airborne signal, be specifically related to a kind of DVOR omnidirectional range reflector net antenna shock mitigation system.
Background technology
DVOR omnidirectional range reflector net is the supporting requisite reception reflect the antenna assembly of airborne signal with transmitter in Civil Aviation System, general construction outside airfield runway near and flight route on each guidance station on, spacing 300 km, for providing the navigation information of exact position to aircraft when taking off and on air route, work in very high frequency band, utilize doppler principle, provide airborne vehicle that relevant device is housed relative to the magnetic azimuth information of this ground installation.
Existing DVOR omnidirectional range reflector net is made up of 5 parts:
1) antenna element: be positioned at above mesh sheet, be connected with Antenna Orbit, comprise 1 antenna element of 48 circumferentially uniform antenna element of diameter 13.5m centered by the mesh sheet center of circle and home position, amount to 49, act on reception and the transmitting of navigation signal, generally directly purchased from overseas specialized company by company of civil aviaton;
2) Antenna Orbit: the antenna element support column comprising track and rail superior portion, for fixed antenna a period of time, and is connected with reflector net;
