Background
The electric trains of the main line railway and the urban rail adopt a contact current collection (collecting) mode of a pantograph and a contact net, wherein the contact net is divided into a flexible contact net and a rigid contact net. The main line railway mostly adopts pantograph and flexible contact net mode, and the urban rail adopts pantograph and flexible contact net mode except that, still adopts pantograph and rigid contact net mode, in addition, still receives the contact current collection mode of collector shoe (collector shoe) and third rail (power supply rail). As the name implies, flexible catenary systems are flexible systems, while third rail and rigid catenary systems are rigid systems. Flexible systems are usually subjected to high tension in addition to the contact forces of the pantograph, whereas rigid systems are subjected to contact forces only and hardly to tension. Compared with a flexible system, the rigid system has the obvious advantages of simple structure, large current-carrying capacity, reliability, durability and the like, so that urban rail trains such as subways and light rails and (short stator) maglev trains generally adopt a contact current collection mode of the rigid system of a collector shoe (collector shoe) and a third rail (power supply rail), but the power performance matching problem of the structural form of the collector shoe (collector shoe) and the third rail (power supply rail) is not well solved, the shaking and the vibration generated in the running of the trains can be directly transmitted to the third rail (power supply rail) through the collector shoe (collector shoe), not only noise is generated and the environment is polluted, but also the current collection performance and the service life of the collector shoe (collector shoe) and the third rail (power supply rail) are seriously influenced, and the good exertion of the advantages of the rigid system is seriously restricted.
