Problems solved by technology

This method of marking and locating one by one can usually meet the test requirements, but it will bring great difficulty to the marking process when encountering a structure like the inclined vertical tail, because the height of the inclined vertical tail itself is relatively high, and the test after tilting outward It is very inconvenient for personnel to operate, and this marking process will consume a lot of time

Abstract

The invention discloses a projection-type point distribution position device of aircraft ground vibration experiment. The projection-type point distribution position device comprises a slide film, a card support, a card adjustment mechanism and / or light source projection equipment, wherein the slide film is provided with an airfoil profile line or a plurality of typical positioning points, sensorarrangement points are arranged at predetermined positions of the slide film, the card support is used for fixedly installing the slide film, the card adjustment mechanism is used for installing the card support and can drive the card support to move and / or rotate, and the light source projection equipment is used for allowing a light beam to transmit through the aerofoil profile line or the typical positioning points on the slide film and project an aircraft airfoil to be provided with sensors.

Description

technical field [0001] The application belongs to the field of structural dynamics tests, and in particular relates to a projection type positioning device for aircraft ground vibration tests. Background technique [0002] In order to grasp the structural dynamic characteristics of the aircraft, it is necessary to conduct a ground vibration test (full aircraft ground resonance test), and use the test results to correct the theoretical calculation model. During the implementation of the test, a large number of sensors need to be arranged on the surface of the aircraft to measure the frequency and mode shape of the whole aircraft. In previous aircraft ground vibration tests, the sensor points needed to be measured and positioned by the test personnel one by one according to the provided coordinates, and marked for the next step of pasting the sensors. This method of marking and locating one by one can usually meet the test requirements, but it will bring great difficulty to t...
