supporting block

Rail transit in our country is now in a rapidly construction and development period, so the application of supporting block track has a bright future.

目前，我国轨道交通正处于快速建设和发展时期，其应用前景十分广阔。

Research on Dynamic Characteristics of Supporting Block Track on Bridge in Urban Rail Transit

城市轨道交通桥上承轨台式轨道结构动力特性研究

It has a supporting block in the centre with central transmission. The sludge is removed by spontaneous imbibition through flat nozzle.

该刮泥机为中心支墩式中心传动，扁吸嘴自吸式吸泥；

Vibration and Noise Strength of the Elastic Supporting Block Track

弹性支承块轨道振动与噪声强度关系分析

both the supporting block and the stop pins can prevent the thrust bearing pads and the supporting pad from being deviated;

支撑块和限位销都可防止推力轴瓦与支撑垫在工作中产生偏移；

Temperature stress of spatial grid and design of supporting block

空间网架的温度应力和支座设计

Low vibration and noise track structure has three types: elastic fastener system, elastic supporting block and floating slab.

减振降噪型轨道结构分三类：弹性扣件、弹性支承块和浮置板。

and the radial central line of each supporting block lags behind the geometric central line of the corresponding thrust bearing pads.

每个支撑块的径向中心线滞后相应推力轴瓦的几何中心线。

Based on comprehensive investigation and documents, the paper takes the supporting block track as research object, researching its dynamic characteristic from ideas of systemic and an overall consideration of wheel-rail, tract-bridge interaction.

本文在大量的文献调研基础上，以桥上支承块承轨台轨道结构为主要研究对象，从系统的观念出发，综合考虑轮轨相互作用与桥轨相互作用，对其动力特性进行研究。

Research purposes: This paper finds the thickness of solid slib which replaced slab of elastic supporting block ballastless track.

研究目的：找到与不规则形状形式的弹性支承式无砟轨道道床板等效的实体板的等效厚度。
