Ballast bed anti-vibration pad for rail transit
The invention discloses a track bed anti-vibration pad for rail transit, which comprises a base plate base body and a plurality of boss structures arranged on one side surface of the base plate base body, and the boss structures comprise large boss structures distributed at the central stress position of the track bed anti-vibration pad and small boss structures surrounding the peripheries of the large boss structures. Compared with the prior art, the track bed anti-vibration pad has the positive effects that after the track bed anti-vibration pad is used for a long time, the rigidity of the large boss structure changes slowly, and compared with an existing track bed anti-vibration pad with a plurality of boss structures with the same size, the center position of the track bed anti-vibration pad is thinned, the speed is low, and the service life is long. Besides, as the load is gradually increased, the contact area between the roadbed and the boss of the anti-vibration pad is small, and then the contact area is gradually and slowly increased, compared with an existing ballast bed anti-vibration pad with a plurality of bosses of the same size, the rigidity of the anti-vibration pad is slowly changed, a certain anti-vibration and noise-reduction effect can be provided, meanwhile, the settlement amplitude of a train is small, and the comfort of passengers is improved.
本发明公开了一种轨道交通用道床减振垫，包括垫板基体和在垫板基体的一侧面设置的多个凸台结构，所述凸台结构包括分布在道床减振垫中心受力位置的大凸台结构和包围在大凸台结构四周的小凸台结构。与现有技术相比，本发明的积极效果是：本发明的道床减振垫经长时间服役后，大凸台结构刚度变化缓慢，相比现有由大小相同的若干个凸台结构的道床减振垫的中心位置变薄速度慢，使用寿命长。另外，随着载荷逐渐增大，开始路基与减振垫凸台接触面积小，然后接触面积逐渐缓慢增大，相比现有由大小相同的若干个凸台结构的道床减振垫的刚度变化缓慢，能够提供一定的减振降噪效果，同时列车沉降幅值小，提高乘客舒适性。
