Abstract：Aiming at the shortcomings of the traditional connection methods for aircraft access panels ， such as low maintenance efficiency and poor reusability，a wedge mechanism which is composed of a flexible wedge block and a wedge groove was designed. The engagement and disengagement of the wedgeblock mechanism were achieved by preload force generated from the cooperation between the hinge rotation offlexible wedge block and the wedge groove，and the threaded holes of diffrent diameters on the flexible wedge block and the wedge groove. The pseudo-rigid body method and integral method were adopted to establish the deformation model and mechanical model，and the mechanical characteristics of key design parameters were analyzed. Simulation and physical tests show that the wedge mechanism has the ability to resist loosening and disengagement under medium and low-frequency working conditions.
