A stiffness simulation test device actively applying a support reaction force and deformation

Abstract

The application provides a rigidity simulation test device for actively applying counterforce and deformation, comprising: an active displacement control actuating cylinder connected with a flap through an adapter; a connecting section connected with a certain group of joints on the flap through a connecting piece; a supporting beam installed on a supporting column, wherein a vertical sliding rail is arranged on the supporting beam, and a guide block capable of relative movement is arranged in the sliding rail; a following section, one side of the following section being connected with the guide block, and the other side of the following section being provided with a bending moment actuating cylinder connected with the connecting section, wherein the bending moment actuating cylinder is connected with the connecting section through a force sensor; and a following deformation actuating cylinder, which is arranged in parallel with the active displacement control actuating cylinder and connected with the following section. The simulation test device can ensure the authenticity of the rigidity deformation simulation of the aileron and other test pieces, and solve the problems of difficulty in rigidity calibration of the flap and other test pieces and large measurement error.
