Problems solved by technology

[0002] In the composite wing project, due to the close distance between the hanging middle joint, the hanging inner lower joint, and the hanging outer lower joint of the hanging joints, the load cannot be applied through the actuator
In order to achieve accurate and reliable loading of the aircraft wing suspension joints, it is necessary to simulate the static force and fatigue damage tolerance of the composite wing full-scale structure test suspension connection area, and to test the fatigue damage tolerance that can be changed in real time The direction of the load in the experiment, but there is no relevant loading device for the hanging joint on the market

Abstract

The invention discloses a loading device of a wing hanging connector. The loading device is used for guaranteeing that engine load is precisely transmitted to a hanging connector of a wing, wherein the hanging connector comprises an upper connector body, an inner side lower connector body, an outer side lower connector body, a lateral connector body and a rear connector body, the loading device comprises a hanging dummy member, a heading connector body, a matching lateral connector body and a vertical connector body, and the hanging dummy member is connected with the hanging connector body; the heading connector body is arranged on the hanging dummy member and is used for transmitting heading load to the inner side lower connector body, the outer side lower connector body and the rear connector body; the matching lateral connector body is arranged on the hanging dummy member and is used for transmitting lateral load to the lateral connector body; and the vertical connector body is arranged on the hanging dummy member and is used for transmitting vertical load to the inner side lower connector body, the outer side lower connector body, the rear connector body and the lateral connector body. The loading device can ensure that the engine load is precisely transmitted to the hanging connector of the wing, and can change the load direction in real time in a fatigue damage tolerancetest.

Description

technical field [0001] The invention relates to the field of mechanical performance testing of aircraft structures, in particular to a loading device for wing suspension joints.
