Nonlinear energy trap damping adjusting structure

The invention discloses a nonlinear energy trap damping adjusting structure which comprises a flange adjusting module and a pressure deformation module. The flange adjusting module comprises two supporting sleeves, damping adjusting sleeves are arranged on the inner peripheries of the supporting sleeves correspondingly, and the inner conical surfaces of the supporting sleeves are in extrusion sliding fit with the outer conical surfaces of the damping adjusting sleeves. The pressure deformation module comprises a shaft sleeve inner ring and a shaft sleeve outer ring, the shaft sleeve inner ring and the shaft sleeve outer ring are arranged on the inner circumference of the corresponding supporting sleeve, and the outer conical surface of the shaft sleeve inner ring and the inner conical surface of the shaft sleeve outer ring in one sleeve are in extrusion sliding fit; the shaft sleeve inner ring is in clearance fit with the shaft; the extrusion sliding fit direction of the inner conical surface of the supportin
