Steel rail dynamic vibration absorber based on acoustic black hole and vibration reduction steel rail
The invention relates to the technical field of rail vibration reduction, in particular to a steel rail dynamic vibration absorber based on acoustic black holes and a vibration reduction steel rail. The steel rail dynamic vibration absorber comprises a shell, a connecting block, an acoustic black hole damping vibrator and a tip damping layer. The outer wall of the shell is provided with a connecting part used for being connected with the inner side and/or the outer side of a steel rail. The connecting block, the acoustic black hole damping vibrator and the tip damping layer are all arranged in the shell, the connecting block is connected with the inner wall of the shell, the acoustic black hole damping vibrator is installed on the connecting block, and the tip damping layer is arranged at the tip of the acoustic black hole damping vibrator. The vibration reduction steel rail comprises the steel rail dynamic vibration absorber. The control efficiency is high, the frequency range is wide, the structure is simple, the robustness is high, the vibration reduction effect can be further improved, the requirement for rail vibration reduction of the tramcar can be further met, and meanwhile a comfortable living environment is provided for residents along the line.
本发明涉及轨道减振技术领域，具体涉及一种基于声学黑洞的钢轨动力吸振器及减振钢轨。钢轨动力吸振器包括外壳、连接块、声学黑洞阻尼振子和尖端阻尼层。外壳具有内腔，外壳的外壁设有用于与钢轨内侧和/或外侧连接的连接部。连接块、声学黑洞阻尼振子和尖端阻尼层均设于外壳内，连接块与外壳的内壁连接，声学黑洞阻尼振子安装于连接块，尖端阻尼层设置于声学黑洞阻尼振子的尖端。减振钢轨包括上述钢轨动力吸振器。其控制效率高、频率范围宽、结构简单、鲁棒性高，可进一步提升减振效果，能够进一步满足有轨电车钢轨减振的需要，同时为沿线居民提供一个舒适的居住环境。
