This invention provides a vibration-damping and noise-reducing track structure for RGV (Remotely Resistant Vehicle). The RGV vibration-damping and noise-reducing track structure includes: a vibration-damping base; two tracks, which are mounted on top of the vibration-damping base via multiple sets of fixing brackets. Each set of fixing brackets has fixing bolts installed on its top. The vibration-damping base includes a support structure, a vibration-damping structure, and a wear-resistant structure. The wear-resistant structure is installed between the support structure and the wear-resistant structure, and the vibration-damping structure is a rubber damping pad; filling openings are located at both ends of the tracks, and the interior of the filling openings is filled with a filling structure, which is made of foam plastic. Each track has a sliding opening on its top. The vibration-damping and noise-reducing track structure for RGV provided by this invention can effectively isolate vibration transmission between the track and the foundation, reducing ground vibration and noise propagation, reducing ground vibration amplitude by 30%-40%. Simultaneously, the filling structure can absorb noise, improving the noise reduction effect.
