Problems solved by technology

Although the research on the safety of train operation under complex wind environment has received widespread attention, it is limited to theoretical analysis and numerical simulation, and still lacks experimental verification, and there are few tests specifically aimed at the aerodynamic characteristics of high-speed railway vehicle-bridge systems under strong winds. The complexity and inconvenience of the power cable test of the moving train in the cave seriously restricts the progress of related research

Description

technical field [0001] The invention relates to a mobile train power train power test system, in particular to a mobile train wireless power test system. Background technique [0002] The rapid development of high-speed railway is an important manifestation of national economic development and national strength enhancement. Although the research on the safety of train operation under complex wind environment has received widespread attention, it is limited to theoretical analysis and numerical simulation, and still lacks experimental verification, and there are few tests specifically aimed at the aerodynamic characteristics of high-speed railway vehicle-bridge systems under strong winds. The complexity and inconvenience of the power cable test of the moving train in the cave seriously restricts the progress of related research. [0003] Therefore, it has become an urgent technical problem to study a new type of mobile train wireless power test system. Contents of the inve...
