Disclosed are a method for improving overall performance of a rail vehicle bogie and a suspension damping system. The system rigidity of a torque arm node is adjusted by changing and adjusting torque arm node parameters so as to lower the longitudinal rigidity and the deflection rigidity of the torque arm node; meanwhile the axial rigidity is increased, such that a reduction in the torsional rigidity of the torque arm node is avoided. The structure of a vertical stop is changed to lower the vertical rigidity of a primary suspension. The structure of a supporting ball joint of an anti-side-roll torsion bar is changed to prevent the axial movement of the anti-side-roll torsion bar. The structure of a traction ball joint of a traction rod system component is adjusted to control the non-linear rigidity of the traction ball joint such that the non-linear rigidity of the traction ball joint has a smooth transition. The longitudinal rigidity, axial rigidity, torsional rigidity and deflection rigidity of the entire bogie are adjusted by changing the torque arm node and the vertical stop of the primary suspension system, changing the structure of the supporting ball joint of the anti-side-roll torsion bar of a secondary suspension system and changing the structure of the traction ball joint, such that the overall performance of the bogie is further improved.
