The invention relates to the technical field of floor vibration reduction, in particular to a vibration reduction floor, a vibration reduction assembly, a railway vehicle and a control method. According to the vibration reduction floor, a vibration reduction element is arranged between the bottom of the floor body and a bottom frame and provided with a vibration reduction air bag, the vibration reduction air bag is connected with an air path, and pressure borne by the floor body is detected through a pressure detection element, the control unit is connected with the pressure detection element and the air path, and the control unit is used for controlling the air path to inflate and deflate the vibration reduction air bag according to the pressure detected by the pressure detection element, so that the active vibration reduction effect of the floor is achieved. The control unit inflates and deflates the vibration reduction air bag through the air path according to the bearing pressure of the floor, the rigidity of the vibration reduction element is actively and adaptively adjusted, vibration transmitted to the floor by the vehicle body is reduced, and thus the efficient vibration reduction requirement of the floor under different loads is met, floor vibration radiation noise is reduced, efficient control over noise in the compartment is achieved, and the riding comfort is improved.

    本发明涉及地板减振技术领域,尤其涉及一种减振地板、组件、轨道车辆以及控制方法,该减振地板,通过在地板本体的底部与底架之间设置减振元件,减振元件设有减振气囊,减振气囊连接有气路,并通过压力检测元件检测地板本体所受压力,通过控制单元与压力检测元件以及气路分别连接,利用控制单元根据压力检测元件所测得的压力,控制气路对减振气囊充放气,以实现地板的主动减振效果。控制单元根据地板的承受压力通过气路对减振气囊充放气,实现减振元件自身刚度主动适应性地调整,减小了车体向地板传递的振动,从而实现地板不同载荷时的高效减振需求,进而减小了地板振动辐射噪声,实现高效率车厢内噪声控制,提高乘坐舒适性。
