A elastic wheel noise reduction damper and the assembly and installation method therefor, comprises an annular transition plate and a damper body. The damper body comprises metal plates successively stacked and rubber damping layers filled between the metal plates, the plurality of metal plates are fixedly connected by rivets and also connected with the annular transition plate by rivets, and the riveting force of the rivets does not act on the rubber damping layers. Which enables most of the mass of the damper to fully resonantly deform, greatly increases the number of resonant frequencies of the damper, the vibration absorption frequency bandwidth and the energy transfer consumption efficiency. The overall cantilever structure of the damper body and the plurality of independent cantilever resonance branches formed on the slit plate can produce different resonance characteristics, increasing the number of resonance frequencies, and can be designed to match the axial modal frequency of the elastic wheel tyre, which effectively reduces the squeal noise generated by the elastic wheel during driving on small curve sections. Which is beneficial to improve noise reduction reliability and durability.
