Development prospects of electric traction for urban rail transit vehicles
With the advent of the Internet era, computer network technology has had a huge impact on various industries, including the rail transit industry. The combination of computer network technology and vehicle traction control has become an inevitable trend. In fact, based on the current situation, many manufacturers have keenly sensed the importance of computer network technology and have integrated it into the traction control of urban rail transit vehicles to develop traction control systems with network functions, promoting the platformization and networking development of traction control.

Current Application Status of Electric Traction Technology for Modern Urban Rail Transit Vehicles
The electrical traction system is the foundation for the application of electrical traction technology. Due to the fact that urban rail transit vehicles use the third rail power supply method, the overall level of the corresponding electrical traction system is extremely high and must meet certain standards in all aspects. In an electrical traction system, the constant gravitational force of electrical traction must always be maintained within a certain range, usually with a constant traction force of 346KN and a natural traction force of 230.2KN. At the same time, there are certain conditions for the electric oxygen traction of rail transit vehicles,
Overview of the Development of Electric Traction Technology for Urban Rail Transit Vehicles
The birth of rail transit vehicles is based on the technical innovation of the steam engine and the official emergence of the railway. Its traction technology has gradually realized the transition and transformation from the steam engine to the internal combustion engine and then to the electric power. At present, the electric traction technology has become the core technology of urban rail transit vehicles.
Traction system: Era Electric is in a leading position
The electric traction transmission system is the power source of high-speed trains, equivalent to the "heart" of high-speed trains. Due to relatively high market barriers, the market was primarily occupied by domestic joint ventures of foreign companies such as Siemens and Alstom in the early stages.
New market size of up to 3 trillion yuan, urban rail transit industry chain enterprises welcome more opportunities
As early as the 2008 economic crisis, the government spent huge amounts of money to increase the construction of major infrastructure such as railways and highways. Rail transit investment was an important lever to hedge against economic decline. Faced with the current economic difficulties, the government has once again increased the construction of rail transit, and at this time, the rail transit sector deserves special attention.
Breaking through key technologies and entering the high-speed track through urban rail construction
Urban rail transit has a huge impact on promoting urban structural adjustment, urban layout integration, land development and utilization, as well as the sustainable development of cities and transportation. The picture shows the underground space complex of Wuhan Optics Valley Square planned and constructed by China Railway Fourth Engineering Group Corporation.
