摘要

以轮轨摩擦自激振动理论和轨面不平顺反馈振动理论为基础，结合钢轨波磨与轨道振动能量回收两个研究方向，通过建立考虑钢轨波磨的“车轮-钢轨-吸振器”振动分析模型与轨道振动俘能器分析模型，研究了不同波深与波长的钢轨短波波磨对轨道振动俘能器的输出功率的影响规律。分析结果显示，波磨深度的增大会导致轮轨接触力和轨面垂向加速度的振幅增大，但不会影响钢轨的主振频率。波磨波长的增大会导致轮轨接触力和轨面垂向加速度的振幅先增大后减小，钢轨的主振频率随波磨波长的增大而减小。轨道振动俘能器的输出功率会受到波磨深度和波长的影响，表现为波长不变时，波深增加，俘能器的输出功率提高。波深不变时，波长增加，俘能器的输出功率先增大后减小，但仍大于光滑轨道上俘能器的输出功率，并且，采用小波包分解方法得到小波包能量值与波磨波长几乎呈线性关系。上述分析结果表明，该轨道振动俘能器在高效回收轨道振动能量的条件下，能有效地监测钢轨波磨的产生过程和预测钢轨波磨的近似波长。

Abstract

The influence of short-pitch rail corrugation on the power generation performance of a rail vibration energy harvester is studied based on the theories of the wheel-rail friction self-excited vibration and the feedback vibration of corrugated irregularity. A numerical model of the wheel-rail-vibration absorber system which considered the short-pitch rail corrugation is established to simulate the rail vibration. The power generation performance analysis of rail vibration energy harvester is carried out based on this wheel-rail-vibration absorber model. The analysis results show that the amplitudes of wheel-rail contact force and vertical vibration acceleration of rail surface increases with the increasing of the rail corrugation depth, and the rail corrugation depth does not affect the main vibration frequency of the rail. With the increase of the rail corrugation wavelength, the oscillation amplitudes of the wheel-rail contact force and the vertical vibration acceleration of rail surface increase first and then decrease. The main vibration frequency of the rail decreases with the increasing of the rail corrugation wavelength. The depth and wavelength of rail corrugation have significant effects on the power generation performance of the rail vibration energy harvester. The output power of energy harvester increases with the increasing of the rail corrugation depth when the rail corrugation wavelength is fixed. With the increase of the rail corrugation wavelength (depth is fixed), the output power of energy harvester increases first and then decrease. Moreover, the energy value of wavelet packet obtained by using wavelet packet decomposition method is almost linearly related to the rail corrugation wavelength. To sum up, the rail vibration energy harvester can effectively monitor the generation process of rail corrugation and predict the approximate wavelength of rail corrugation, and it is beneficial for improving the energy recovery efficiency of rail vibration.
