Abstract A new electromagnetic-collision hybrid damping method for vibration reduction was proposed. Through theoretical derivation, the dynamic model of a vibration system with hybrid damping was established. Through tests, curves of the system’s free vibration, vibration with collision damping and vibration with electromagnetic-collision hybrid damping under the excitation of the same initial displacement were measured, respectively. The test results verified the correctness of the vibration reduction effect of the hybrid damping system and theoretical calculation. The test results showed that compared to free vibration, collision damping or electromagnetic-collision damping can accelerate reducing a system’s vibration amplitude, and vibration reduction effect of electromagnetic-collision hybrid damping is more obvious. Finally, influence laws of different structural parameters on vibration reduction effect of a hybrid damping system were obtained with the theoretical model to perform its optimization design.
