By Ping Wang

High-speed turnouts, a key know-how for high-speed railways, have an exceptional effect at the secure and good working of high-speed trains. Design of High-Speed Railway Turnouts: thought and purposes, comprehensively introduces the technical features and requisites of high-speed turnouts, together with layout theories and strategies of turnout format geometry, wheel and rail kin, music stiffness, welded turnout, turnout conversion, turnout parts, and manufacture and laying applied sciences of turnouts.

Analyzing the operational difficulties of China’s high-speed turnout specifically, this ebook discusses the regulate of constitution irregularity, country irregularity, geometrical irregularity and dynamic irregularity through the layout, manufacture, laying, and upkeep of turnouts. on the finish of this reference publication, the writer offers high-speed turnouts administration tools, upkeep criteria, trying out and tracking know-how, and upkeep know-how. Design of High-Speed Railway Turnouts: thought and Applications will let railway technicians around the globe to increase an in-depth wisdom of the layout, manufacture, laying, and upkeep expertise of high-speed turnouts.

  • The first ebook on the earth to concentration explicitly on high-speed turnouts, together with layout, development, upkeep and administration of excessive pace turnouts
  • Expounds the idea of vehicle-turnout method coupling dynamics intimately, aligning this with a number of examples of computation, and examines the result of dynamic experiments which validate the theory
  • Written by means of Ping Wang, who's well-known as a number one researcher and major developer of high-speed turnouts in China

Sample text

In addition to meeting basic riding requirements, the design of a turnout shall follow the principles below: 1. In all cases, sufficient riding quality and comfort shall be ensured when a train travels in the turnout at a specified speed. 2. The track gauges and spacings of the turnout shall allow unrestricted passage of rolling stock under the most adverse conditions. 3. All parts and relevant accessories of the turnout shall in no case stretch into the construction clearance. 4. Conversion equipment shall be correctly installed.

60. The point rail is somewhat like a common short rail with small expansion displacement. The switch rail is provided with fillers at the heel to reasonably restrict its expansion displacement. 61. , heating type, wind-warming type, and water-warming type) are used. 2. United Kingdom The CWR turnouts manufactured by Balfour Beatty of the United Kingdom mainly involve fixed crossings and swing nose crossings. These turnouts are widely applied to railways for mixed passenger and freight traffic, with a maximum design axle weight of 35 t and highest traveling speeds of 250 km/h.

57. 7. 58) characterized by high efficiency and simple installation. The heating system can automatically remove ice or snow from the slide bedplate on snowy or freezing days. Thus there will be no traffic interruption for manually removing snow or ice that causes conversion failure, guaranteeing normal operation in severe weather conditions. 57 Closure detector. 59 Turnout heater.
