Problems solved by technology

[0004] During the flight of the aircraft, the flaps will undergo corresponding attitude changes. Loading the flaps in this way in the fatigue test of the flap kinematic mechanism cannot accurately reflect the real loading situation of the flaps during the flight of the aircraft, and also It is difficult to truly simulate the loading process of the flap motion mechanism during the flight of the aircraft, making the test data not reliable enough

Abstract

The invention relates to a flap movement mechanism fatigue test device. The device comprises a support; a flap movement mechanism connected to the support; a flap connected to the flap movement mechanism so as to be driven by the flap movement mechanism to move; loading actuating cylinders, wherein piston rods are connected to the flap; and a follow-up supporting plate connected with the base of each loading actuating cylinder and capable of moving along with the flap, so that each loading actuating cylinder is kept vertical to the flap. In addition, the invention relates to a flap movement mechanism fatigue test method which is implemented based on the flap movement mechanism fatigue test device.

Description

technical field [0001] The application belongs to the technical field of fatigue test design of a flap motion mechanism, and in particular relates to a flap motion mechanism fatigue test device and a method thereof. Background technique [0002] The fatigue test of the flap kinematic mechanism is used to provide corresponding data for the study of the failure mode, damage location and damage principle of the flap kinematic mechanism. [0003] At present, when carrying out the fatigue test of the flap kinematic mechanism, the flaps are mostly loaded in a fixed loading manner to simulate the loading of the flaps during the flight of the aircraft. In the fatigue test of the flap kinematic mechanism, the flaps are The loading of the wing load has the following defects: [0004] During the flight of the aircraft, the flaps will undergo corresponding attitude changes. Loading the flaps in this way in the fatigue test of the flap kinematic mechanism cannot accurately reflect the r...
