Using grounded nonlinear energy sinks to suppress lateral vibration in rotor systems

•A piecewise stiffness grounded nonlinear energy sink for rotor system was proposed.•The GNES can suppress transient shock vibration in rotor systems.•The wide-band vibration suppression ability of the GNES was verified.•The GNES was proved to have better vibration suppression ability than absorber....
