Reference 3: Composite Braking Technology for High-Speed Trains

High-speed trains generally employ two composite braking systems: microcomputer-controlled electric braking and friction braking. During braking operations, manual or automatic control is applied. The selected braking system for high-speed trains, especially the composite braking form, must be capable of converting to other forms to ensure smooth connection, thereby enhancing passenger comfort of train operations.

Reference 2: Traction Transmission Technology for High-Speed Trains

The traction equipment of high-speed trains can be controlled to reverse, enhancing adhesion utilization during high-speed operations. The motors in the equipment do not need to change direction. The traction transmission technology used in high-speed trains is an AC-DC-AC converter system.

Locomotive maintenance cycle

The mileage or working time between two identical repairs of a locomotive is called the maintenance cycle. The repair cycle at all levels is a short period of time during which the main components can be safely used between repairs.

Sources and Suppression Measures of Railway Vehicle Noise

When a train is traveling on a railway, there will be various types of noise. Generally speaking, the noise outside the train during operation mainly comes from the following aspects: collision noise between train wheels and rails, friction noise between wheels and rails, friction noise generated when air flows through the surface of the vehicle body, noise generated by friction between contact wire and pantograph, collision noise between car windshields, and compression wave and reflected wave noise generated when the train enters and exits the tunnel.

Repair and maintenance of railway locomotives and vehicles

The safe operation of railways is an important aspect of maintaining social stability. In railway transportation, there are high requirements for the safety and stability of locomotives. If locomotive problems are not detected and dealt with in a timely manner, or locomotive maintenance is not in place, it is easy to cause locomotive operation accidents, leave safety hazards, cause economic losses, and even seriously affect social stability. Therefore, research and analysis were focused on the maintenance and repair of railway locomotives.
