CRH380 - The World's Fastest High-Speed Rail
Design of the Chinese CRH380 train
The design work was carried out in four main categories: schematic drawing, technological planning, structuring and building and experimentation. Based on the analysis, an optimised sub system design was put forward. More than 20 designs were shortlisted and were sent for further optimisation and simulation. Around 1,000 technical tests in 17 specific areas, such as dynamic performance, pantograph, aerodynamic and traction performance, were conducted.
The technology to increase the maximum speed of the train was discovered through research carried out at various universities of China and was fed into the CSR's design.
The body is integrally welded with aluminium alloy and is shaped with a fish head-like structure in the front. The rotating paraboloid wedge structure cuts down aerodynamic resistance and mean energy consumption throughout the runtime. It also increases the amount of regenerated energy.
The new generation high speed electric multiple unit uses the electro pneumatic compound brake mode in which the train will use most of the regenerative braking energy. In the mean time the traction motor will convert the energy into required power by means of a power generator. As a result of this the maximum power of the train increases by 50%, which helps in terms of exceptional energy saving.
The train is designed to be completely vibration free. The train bogies are designed to be safe and reliable. They can withstand and run through a critical speed of 550kmph. They are also incorporated with an advanced noise control technology by using new sound absorbing and insulating materials in the construction.
