Description
Technical field
The invention discloses a kind of complicated opto-mechanical part IMAQ ground simulation platform stance disturbing generating device, specifically
Exactly simulation influences unmanned plane and taken pictures in the air the factor of influence of quality, main analog vibration roll of the present invention and the angle of pitch.
Background technology
Aerial camera is mounted in the precision optical instrument taken pictures on unmanned plane to ground scenery.The vibration of aircraft, air-flow
Change, the change at aircraft pitch angle can all influence the definition of taking pictures of aerial camera, so in order to improve taking pictures for aerial camera
Quality needs to carry out aerial camera many experiments, and practical flight needs the input of substantial amounts of manpower and materials and fund.For
The input of the fund of reduction and shorten the lead time, the influence of aerial camera photographing definition how is influenceed in ground simulation
The factor.Existing electromagnetic vibrator can simulate 0.5 ~ 10khz vibration frequency, but electromagnetic vibrator displacement is smaller can not be real
The angle of pitch now beaten, and although hydraulic vibrator has big displacement to realize the big angle of pitch, but its vibration frequency can only be real
Present 0.5 ~ 200hz.And the frequency of quality of influenceing to take pictures is higher than 50hz.
How the big angle of pitch can be realized in laboratory, and and can realizes big vibration frequency, is aerial camera ground appearance
State disturbing generating device urgent problem.
The content of the invention
The defects of for prior art, the invention provides a kind of complicated opto-mechanical part IMAQ ground simulation platform appearance
State disturbing generating device.The invention discloses a kind of complicated opto-mechanical part IMAQ ground simulation platform stance disturbance to fill
Put, emulation platform includes silent flatform, DC servo motor, and Hooke is hinged, hydraulic stem, displacement transducer, spherical pair, moving platform；
Moving platform has including pendulous device and vibrating device；Vibrating device is made up of electromagnetic vibrator and shake table；DC servo
Motor connected bolt with Hooke's hinge and linked with silent flatform, and hydraulic stem is hinged by Hooke and link with silent flatform, Hooke hinge and
Hydraulic stem is linked by bolt, and hydraulic stem is linked by spherical pair and moving platform；Displacement transducer is fixed on hydraulic stem, electromagnetism
Shaking platform is bolted with moving platform.
Complicated opto-mechanical part IMAQ ground simulation platform stance disturbing generating device is aerial camera terrestrial air ring
Border analogue means.In-flight simulation can be carried out to aerial camera in laboratory, and can be the airborne performance of aerial camera
Important parameter is provided, it detected using practical flight so as to reduce, and then human and material resources and fund can be reduced
Investment, and shorten the lead time.
The present invention is to realize it is being to realize to detect aerial camera in laboratory, and its major technique basis is simulation
The skyborne vibration of aircraft, pitching.Scenery is taken pictures by tested camera, analyzed, to all technical of aerial camera
Make detailed comprehensive evaluation.
