Embodiment

[0028] Such as Figure 1-Figure 3 As shown, a deformation driving detection device of a deformable smart wing includes a body part of the deformable smart wing and a vibration detection part.

[0029] The body part of the deformable smart wing includes a deformable smart wing model 1, a wing fixed support 7 and a test bench 11. The test bench is an aluminum profile seat for placing the body part of the deformable smart wing and the vibration detection part. It plays a supporting role; the overall manifold of the deformable smart wing model simulates the NACA-0012 airfoil, and the structure is composed of three parts: leading edge part 1-1, spoiler part 1-2, trailing edge part 1-3 ; wherein the leading edge part 1-1 and the trailing edge part 1-3 are non-deformed parts; the spoiler part 1-2 is a deformed part, and its basic structure is supported by spine bending beams and longitudinal beams, and the inner layer is a honeycomb grid structure; Polyurethane rubber is poured into...

Abstract

The invention discloses a deformation driving detection device and a method for a deformable intelligent wing, which comprises a deformable intelligent wing body part and a vibration detection part, the deformable intelligent wing body part comprises a deformable intelligent wing model, the vibration detection part comprises a scanning type laser vibration meter, a digital decoder, a speckle alumpowder, a conditioning amplifying circuit, a charge amplifier, an A / D collection card, a laser displacement sensor, an accelerometer, and a computer, the laser displacement sensor and the accelerometer detect synchronously at the same time for comparison; exciting the deformable intelligent wing model and the scanning type laser vibration meter to scan, the data is decoded by the digital decoder and transmitted to the computer to display the vibration mode in a 3D animation or a 2D color picture on the display device, so that realizing the deformable intelligent wing deformation detection visualization.

Description

technical field [0001] The invention relates to the field of deformation detection of a deformable smart wing, in particular to a deformation driving detection device and method of a deformable smart wing. Background technique [0002] With the improvement of people's requirements for the maneuverability, fuel economy and stability of aircraft, the traditional wing design method has become more and more difficult to meet the demand. For example, using the crank linkage mechanism to adjust the angle change of the flap can achieve the effect of increasing the lift of the aircraft to a certain extent, but the shape change of the wing during this change process is discontinuous, which causes the wing to show the airflow The discontinuous change seriously affects the flight stability of the aircraft. Therefore, the concept of deformable smart wing is highly praised. The deformable smart wing can automatically change the shape of the wing with changes in atmospheric disturbance,...
