Beschreibung
Zusammenfassung:	The invention provides a nonlinear energy trap device. The nonlinear energy trap device comprises an axial telescopic mechanism, a vertical telescopic mechanism, a steering mechanism and a sleeve, the axial telescopic mechanism, the vertical telescopic mechanism and the steering mechanism are all installed in an inner cavity of the sleeve. The axial telescopic mechanism elastically reciprocates in the axial direction of the sleeve, the vertical telescopic mechanism elastically reciprocates in the direction perpendicular to the axial direction of the sleeve, and the steering mechanism is connected between the axial telescopic mechanism and the vertical telescopic mechanism; the steering mechanism comprises a ball screw, an eccentric cam, a rectangular frame, a ball nut and a limiting bearing. By means of the mass amplification effect generated when the eccentric cam rotates in a reciprocating mode, large dynamic apparent mass needed by frequency modulation damping is provided, linear and nonlinear double-rigid
