Problems solved by technology

However, some parts of the test aircraft (such as the center wing, belly landing gear, etc.) cannot be buckled by the reverse counterweight method due to structural layout restrictions, making the traditional buckle method unable to solve new problems

Abstract

The application provides an aircraft test device, a restraint and loading method, and a tare and loading method. The device includes a support structure, and has a cavity, and a plurality of balls are arranged in the cavity; a hydraulic actuator is arranged on the support structure. The upper surface of the adjusting structure, one end is connected with the end of the hydraulic actuator that is far away from the support structure; the load sensor is connected with the other end of the adjusting structure; the connecting end of the test piece is connected with the load sensor; the displacement sensor is connected with the connecting end of the test piece Connection, used to detect the displacement of the connection end of the test piece.

Description

technical field [0001] The present application relates to the technical field of aircraft structural strength, and specifically provides an aircraft test device, a restraint and loading method, and a weighting and loading method. Background technique [0002] When conducting a full-scale aircraft structure ground strength test, it is necessary to constrain the aircraft in a fixed coordinate system. The method of constraining is usually to design a six-degree-of-freedom statically determinate constraint at the landing gear with a strong concentrated load capacity of the aircraft. The composition of statically indeterminate constraints is usually three vertical constraints on three landing gears in the vertical direction, two landing gear headings and one lateral displacement constraint in the horizontal direction. By adjusting the displacement of the six constraint points The overall coordinate position of the aircraft can be uniquely defined. [0003] In the vertical restra...
