Microporous structure vibration isolation pad for rail transit
The invention provides a micro-pore structure vibration isolation pad for rail transit, which is characterized by comprising a plate-shaped body part, a plurality of micro-pore structures and a plurality of vibration isolation pads, the body part is arranged on the base, the plurality of protruding parts are distributed on the surface of one side of the body part, the body part and the protruding parts are made of microporous rubber, the shape of each protruding part is any one or a combination of several of a hemisphere, a cylinder, a cone and an ellipsoid, and the thickness of each protruding part is 5mm-35mm. Compared with a solid vibration isolation pad with protrusions in the prior art, the vibration isolation pad has the advantages that the static rigidity is lower, the specific gravity is small, the rigidity is lower, the high-frequency dynamic rigidity is stable, and the vibration isolation pad is more suitable for being used as a rail transit vibration isolation pad.
本发明提供了一种轨道交通用微孔结构隔振垫，其特征在于，包括：本体部，呈板状；以及多个凸起部，分布在本体部的一侧表面上，其中，本体部与凸起部由微孔橡胶构成，凸起部的形状为半球体、柱体、锥体、椭球体中的任意一种或几种的组合，凸起部的厚度为5mm‑35mm。相较于现有技术中的实心且带有凸起的隔振垫，本发明的隔振垫实现了更低静刚度的同时具有较小的比重的效果，且具有刚度更低、高频动态刚度稳定的优点，更适宜作为轨道交通隔振垫应用。
