Abstract

The invention belongs to the technology of aircraft follow-up loading and particularly relates to an aircraft rear body dynamic load follow-up loading testing device. The device is characterized in that the vibration table of the device is connected to a movable frame through rotary shafts at two ends of the vibration table, two vertical guide rails are disposed at each of the two ends of the movable frame and connected with a base, a hydraulic actuator cylinder is fixed on each of the two sides of the base, a piston rod is connected with the movable frame, a hydraulic locking device is mounted on the upper end cover of the hydraulic actuator cylinder, a hydraulic bulb vibration excitation rod is mounted on the movable core of the vibration table, the head of the hydraulic bulb vibration excitation rod is connected with an aircraft rear body, a displacement sensor is fixed on the static table surface of the vibration table, and a pull line is fixed with the aircraft rear body. The aircraft rear body dynamic load follow-up loading testing device has the advantages that the vibration table tracks the deformation of the aircraft rear body at any time to apply vibration excitation force to the same, the vibration excitation force is vertical to the tangent plane of an aircraft rear body loading point, static and dynamic loads are applied in a combined manner, and testing effect is close to actual situations.

Description

technical field [0001] The invention belongs to the aircraft loading test technology, in particular to a dynamic load follow-up loading test device for the rear fuselage of the aircraft. Background technique [0002] Because the rear fuselage of the aircraft is subjected to conventional aerodynamic force and sometimes eddy current impact during flight, in order to simulate the load of the rear fuselage more realistically, static and dynamic loads should be applied to the rear fuselage at the same time. However, at present, there is no corresponding test device for the dynamic follow-up loading test of the rear fuselage of the aircraft, especially the combined static and dynamic load loading technology of the rear fuselage of the aircraft is a blank in China, and no such test has been done. Contents of the invention [0003] The purpose of the present invention is: to provide a kind of load that can realize static load, dynamic load combination, especially the follow-up loa...
