Self-energized vibration energy collecting system of electric locomotive bogie

Abstract

The invention discloses an electric locomotive bogie self-energized vibration energy collection system, which comprises a self-energized vibration energy collector, and the self-energized vibration energy collector is used for collecting vertical vibration and / or transverse vibration energy generated by a bogie in the running process of an electric locomotive. The device has the advantages of simple and compact structure, low cost, easiness in implementation and the like.

Description

technical field [0001] The invention mainly relates to the technical field of rail transit, in particular to a self-powered vibration energy collection system for an electric locomotive bogie. Background technique [0002] Electric locomotives obtain electric energy from catenary or electrified rails, and drive trains to run at high speed on the rails through electric motors. Electric locomotives have been continuously developed and applied due to their advantages such as high power, large traction, fast acceleration, cleanliness and environmental protection, and the electrified railway system has also continued to expand. As the speed of electric locomotives continues to increase, the bogie, one of the core components of electric locomotives, plays a vital role in ensuring the stability and ride comfort of the electric locomotive. The bogie is in direct contact with the rails, supporting the car body and ensuring the safe operation of the electric locomotive; the bogie is ...

AI Technical Summary

Problems solved by technology

[0003] At present, sensors or other equipment for testing experiments on the train bogie or the bottom of the train need to be connected to the power system of the electric locomotive, which directly causes inconvenience in operation; and the vibration generated by the bogie when the electric locomotive runs at high speed passes through the spring Shock absorption and filtering, resulting in a waste of vibration resources

[0004] Although existing resonance-based generators can achieve high-power output power generation, such generators are too bulky and not easy to install

Although the non-resonance generator has the advantage of portability, it cannot benefit from the amplified resonance factor, and the power generation efficiency is low; and it is difficult to achieve stable power generation output under the low-frequency vibration generated by the low-speed train when using a single mechanical motion power generation method
