Method for improving damping performance of steel rail damper, and steel rail damper
The invention relates to a method for improving the damping performance of a steel rail damper. A friction energy dissipation surface is formed in a manner of converting vertical vibration into horizontal vibration of a base to dissipate vibration energy, so that the damping performance of the steel rail damper is improved, and a better vibration and noise reduction effect is achieved. The invention further relates to a steel rail damper for realizing the method. The steel rail damper comprises an upper wearing layer, an energy absorption layer, a lower wearing layer and a base, the base comprises a base I and a base II, the base I is elastically connected with the base II through a plate spring, and the contact surface of the lower wearing layer and the base is V-shaped or inverted-V-shaped. The vertical load is decomposed into two reverse component forces in the horizontal direction, so that the base I and the base II are pushed to move reversely, friction is generated between the upper surfaces of the base I and the base II and the lower surface of the lower wearing layer, vibration energy is consumed, and the damping performance of the steel rail damper is improved.
本发明涉及一种增加钢轨阻尼器的阻尼性能方法，通过将垂向振动转化为底座的水平振动的方式，形成摩擦耗能面，以耗散振动能量，从而增加钢轨阻尼器的阻尼性能，以取得更好的减振降噪效果。本发明还涉及一种实现上述方法的钢轨阻尼器，包括：上磨耗层、吸能层、下磨耗层及底座，所述底座包括底座一和底座二，底座一与底座二通过板簧弹性连接，下磨耗层与底座接触面呈V形或倒V形。将垂向荷载分解形成两个水平方向的反向分力，从而推动底座一与底座二反向移动，使得底座一和底座二的上表面与下磨耗层下表面之间产生摩擦，以消耗振动能量，增加钢轨阻尼器的阻尼性能。
