Harmonic number of the front body of the internal mechanical parts of the distribution and distribution of the role
High-speed trains running fast, must have the following conditions: to have high-power traction driving the train to run; require the vehicle light and stable; because the train resistance and the speed is proportional to the square, it must use streamlined body to reduce resistance Series of measures to achieve high-speed train operation; train running fast, but also to stop in time, so high-speed train as ordinary train as brakes and wheel friction to brake, and to use advanced integrated braking means; High-speed trains on the line at high speed, must ensure the safety of operation, which depends on a set to ensure safe operation of the command system, while high-speed railway track, bridge structure and technical conditions must meet the high-speed train high-speed requirements; To provide high-grade travel services, so the need to have the appropriate service facilities; ... ... to meet the above requirements, high-speed trains must be used to achieve high-tech to pay.
The reason is that high-speed trains use the 20th century related areas of high-tech achievements. It combines the essence of a series of disciplines such as mechanical, electronic, control, communication, aerodynamics, environmental protection and so on. It has adopted a variety of new products such as electronic computer, information technology, new material and power electronic components. The railway locomotive manufacturing technology To a new stage, in order to achieve the train running speed of 300 km or more, the world's second only to the aircraft high-speed transport. So what kind of high-tech train?
