A liquid composite rubber pad with a longitudinal high dynamic-static ratio comprises a top plate, a partition plate and a bottom plate which are sequentially stacked up and down, the top plate and the partition plate are connected with an upper rubber layer, a lower rubber layer is connected between the partition plate and the bottom plate, and a hollow upper hydraulic cavity and a hollow lower hydraulic cavity are formed in the upper rubber layer and the lower rubber layer respectively. A liquid channel is communicated between the upper hydraulic chamber and the lower hydraulic chamber, and the upper hydraulic chamber and the lower hydraulic chamber extend in the longitudinal direction. When the liquid composite rubber pile is longitudinally loaded, the liquid cavity on one side is stretched, the other side is compressed, fluid exchange occurs to generate damping, the effects of low static rigidity and high dynamic rigidity in the longitudinal direction are achieved, and the influence on the dynamic-static ratio of the vertical rigidity and the transverse rigidity is small while the high-dynamic-static-ratio longitudinal rigidity is achieved.

    一种纵向高动静比的液体复合橡胶堆,包括依次上下叠置的顶板、隔板和底板,在顶板和隔板连接连接上橡胶层,隔板和底板之间均连接下橡胶层,在上橡胶层和下橡胶层中分别具有中空的上液压腔室和下液压腔室,在上液压腔室和下液压腔室之间连通液体通道,所述上液压腔室和下液压腔室沿纵向延伸。本发明提出的液体复合橡胶堆在纵向受载时一面液体腔拉伸,另一面压缩,发生流体交换产生阻尼,实现纵向方向低静态刚度和高动态刚度的效果,在实现高动静比纵向刚度同时对于垂向和横向刚度的动静比影响较小。
