Abstract

The invention provides a railway vehicle floor and a railway vehicle. The floor comprises an interior floor arranged on a vehicle body floor of the railway vehicle, and a shock absorber is arranged between the interior floor and the vehicle body floor; the shock absorber comprises a vibration isolation plate, vibration isolation units are connected between the vibration isolation plate and an interior floor and between the vibration isolation plate and a vehicle body floor, resonance units extending towards the side where the interior floor is located and/or the side where the vehicle body floor is located are arranged on the surface of the vibration isolation plate, and the resonance units and the vibration isolation units are arranged at intervals. And a gap is formed between the resonance unit and the side where the interior floor is located and/or the side where the vehicle body floor is located. According to the railway vehicle floor, through multi-stage vibration reduction of the resonance unit, the vibration isolation plate and the vibration isolation unit, the vibration isolation efficiency from the vehicle body to the interior floor is greatly improved, the parameter design of multi-stage vibration reduction is achieved, the designability of the vibration isolation performance of the floor is improved, and better riding experience is brought to a user.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle floor and a rail vehicle. Background technique [0002] The rail car interior floor is usually fixed on the car body floor profile by using elastic bodies such as rubber and vibration-damping foam. Although it has a certain vibration isolation performance, it can reduce the transmission of car body vibration to the interior floor. However, the vibration damping structure is simple, the vibration damping efficiency is not high, and the designability of the shock absorber is single, it is difficult to meet different levels of vibration damping requirements, and the designability for different degrees of vibration isolation is insufficient. Contents of the invention [0003] The invention provides a rail vehicle floor and a rail vehicle, which are used to solve the defects of a single vibration damping structure and low vibration damping efficiency in the prio...
