Vibration reduction system for ballast bed, ballast bed slab, ballast bed and track system
According to the vibration reduction system for the ballast bed, the ballast bed slab, the ballast bed and the track system, two vibration reduction modes of the ballast bed resonator and the ballast bed vibration absorber are combined, and due to the fact that the ballast bed resonator is adopted, the ballast bed resonator is provided with the resonance plate capable of changing the overall inherent frequency of the ballast bed slab and the ballast bed; therefore, the vibration frequency of the ballast bed and the inherent frequency of the surrounding environment facility can form a frequency band difference and are not in the same resonant frequency, so that the influence of vibration noise can be avoided or reduced; due to the fact that the ballast bed shock absorbers are adopted, the ballast bed shock absorbers are anti-vibration pads or steel spring vibration isolators or rubber spring vibration isolators and are provided with the elastic units capable of absorbing and reducing the vibration impact energy of train running, the effect of reducing vibration and noise of the track can be achieved. As mentioned above, two vibration reduction modes with different principles are combined, the advantages of the two vibration reduction modes can be complementary, and therefore the more ideal track vibration reduction and noise reduction effect is achieved.
本发明提供一种道床用减振系统、道床板、道床以及轨道系统，结合了道床谐振器以及道床减振器两种减振形式，由于采用了道床谐振器，其具有能够改变道床板、道床整体的固有频率的谐振板，因此能够使得道床的振动频率与周围环境设施的固有频率形成频率段差，不在同一共振频率内，从而能够避免或降低振动噪声的影响；由于采用了道床减振器，其为减振垫、钢弹簧隔振器或橡胶弹簧隔振器，具有能够吸收和降低列车行驶的振动冲击能量的弹性单元，因此能够实现轨道减振降噪的效果。如上所述，本发明结合了两种不同原理的减振方式，两者能够优势互补，从而实现更理想的轨道减振降噪效果。
