The invention belongs to the technical field of vibration data control and recognition of damping elements, and discloses a wire mesh damper for rail transit, a design method and a system. By means of the structure that the limiting barrel is matched with the limiting guide column, the metal wire mesh block can restrain vibration excited by the vertical excitation load when the rail traffic tool actually runs, and buffering of transverse vibration when the rail traffic tool steers, starts and suddenly stops is achieved. And the vibration reduction requirements of the rail traffic tool on different degrees of freedom are met by utilizing different rigidities of the metal wire mesh blocks on various degrees of freedom, and the vibration control requirements of the train under different bearing capacity conditions are met by utilizing the variable rigidity characteristic of the metal wire mesh blocks. The structure of the shock absorber is simplified, the weight of the shock absorber is reduced, external vibration noise is controlled, bidirectional vibration reduction of the metal wire mesh floor shock absorber in three degrees of freedom in the vertical direction, the transverse direction and the running direction of a train is achieved, and the metal wire mesh floor shock absorber adapts to different vibration load characteristics of different degrees of freedom of rail traffic tools.
