Power generation device based on spring oscillator system

The application of magnetorheological equipment and its sensors in high-speed trains is restricted to a certain extent due to the demand for external power supply. Usually, there are different degrees of vibration in the operation of high-speed trains. If the vibration energy is converted into electric energy, it will be beneficial to the wide application of magnetorheological equipment in high-speed trains. In this paper, based on the load characteristics of the anti-yaw damper in high-speed trains, a ring-iron resonant power generation device based on the spring oscillator system is designed by using the amplification effect of the spring oscillator system on the amplitude. In this paper, a vibration test was carried out by an experimental prototype and two control prototypes, and the power generation capacity of the device was verified. The test results show that the maximum power generation of the device designed in this paper is 20.18 watts, which is 98% higher than that of the control group. The average power generation in random vibration is 6 watts, which can meet the power supply demand of magnetorheological damping equipment in high-speed trains.
