Rheda 2000 Track Form Of Smoothness Of The Control Method

High-speed railway is a new mode of transportation in modern society, it has obvious advantages. After the development of high-speed railway, China is the world's fastest developing, comprehensive high-speed railway systems technology country with longest operation mileage and highest operation speed and the biggest under-construction scale. The characteristics of high-speed railway are high speed and high density, as railway track is an important railway transportation technical equipment, high-speed railway requires railway track structure have high ride comfort, high stability and reliability. In this paper, Wuhan-guangzhou high-speed railway was taken as engineering application examples, and put emphasis on the method of controlling the ride comfort of Rheda 2000. The major work is summarized as follows:1. According to the characteristics of high speed and high density, basic requirements of high-speed railway to tracks were extracted, and the significance of smooth control of railway tracks was expounded.2. The components of the Rheda 2000 system used in the construction of Wuhan-guangzhou high-speed railway was introduced and the methord and main point of smooth control in different engineering applications such as roadbeds,bridges,tunnels and transition sections of roads and bridges or tunnels were expounded.3. Concrete method of controlling the ride comfort of tracks in the construction process which contain the long rail static adjustment to optimize the track linetype and dynamic adjustment was expounded.As a summarization of the methods to control the ride comfort of the Rheda 2000 structure, the research results of this thesis was successfully applied in engineering and also provide references for construction control and testing of other similar high-speed railway track structures.
