The invention discloses a rail vehicle loading interface vibration and noise reduction device which comprises an inner floor connected in a rail train carriage through a vibration reduction structure, and seats are arranged on the inner floor. The damping structure comprises a suspension vibration isolation assembly for connecting the inner floor to the side wall of the carriage in a suspension mode and supporting damping assemblies evenly arranged between the inner floor and the bottom face of the carriage. The supporting damping assembly further comprises a supporting leg inserted into the inner floor in a penetrating mode, and the supporting leg is integrally connected with the other end of the seat and connected with the inner floor through the second damping piece. According to the invention, a double-damping structure aiming at the loading interface of the rail train is constructed, the passenger seat and the built-in floor are systematically designed into a double-layer vibration isolation system, the two damping structures actually correspond to the high frequency band and the low frequency band of the vibration of the rail train, and a damping coupling system is formed by referring to the principle of a buoyant raft type double-layer vibration isolation system.

    本发明公开的一种轨道车辆乘载界面减振降噪装置,包括通过减震结构连接在轨道列车车厢内的内地板,所述内内地板上布置有座椅,其特征在于,所述减震结构包括:将所述内内地板悬挂连接在车厢侧壁上的悬挂隔振组件、均匀布置在所述内内地板与车厢底面之间的支撑减震组件。所述支撑减震组件还包括穿插于所述内地板中的支腿,所述支腿一体连接所述座椅另一端通过所述第二减震件与所述内地板连接。本发明构建了一种针对轨道列车乘载界面的双重减振结构,将乘客座椅、内装地板系统化设计成为双层隔振系统,这两部分减振结构实际上对应了轨道列车振动的高频段与低频段,参考浮筏式双层隔振系统原理形成减震的耦合体系。
