description The invention discloses a rigidity and damping anisotropic four-degree-of-freedom nonlinear energy trap vibration reduction system which comprises a bearing face, a supporting column, a mass block, a support and at least three groups of springs and dampers, the support is arranged on the bearing face and supports the mass block, one end of each group of spring and damper is connected with the mass block, and the other end of each group of spring and damper is connected with the other end of each group of spring and damper. The extension line of the central axis of each group of springs and damper does not pass through the mass center of the mass block, so that the elastic restoring force of each group of springs is far away from the mass center of the mass block to form a force arm, and then the torque opposite to the torque direction of the mass block is generated. The change of the deflection angle of the mass block can be inhibited, the optimal tuning of three-way translation and torsional frequency is rea
