The damping ring wheel was proposed to suppress the occurrence of rail corrugation and extend the service life of rails and wheels.The threedimensional finite element models consisting of damping ring,wheelset,rail and sleepers were established based on the theory of corrugations generated by frictional selfexcited vibration caused by saturated creep force in small radius curved track.The complex eigenvalue method was used to study the influence of damping ring,damping coefficient,installation position of damping ring and width of singleside damping ring on rail corrugation.The results show that the wheel with damping ring can effectively suppress the generation of corrugation and the ability of damping ring to suppress the rail corrugation is increased with the increase of damping coefficient.The rail corrugation can be completely eliminated when damping coefficient is larger than 1×10-3.The installation position of the damping ring has no obvious influence on the ability of suppressing corrugation.When the damping ring is installed on the shaft side,the width variation of the damping ring has no obvious influence on the ability of suppressing corrugation.When the damping ring is installed on the outer side,with the increase of the width of the damping ring,the ability of suppressing corrugation of the damping ring wheel is first increased and then decreased,that is,there is an optimal damping ring width,which makes the ability of suppressing corrugation of the damping ring wheel the best.
