道岔轨道减振器是在地铁及轻轨道岔区使用的轨道减振产品,其结构形式上类似于普通剪切型轨道减振器,在不改变道岔原有设计的基础上通过加装该产品能够有效降低行车所产生的振动和噪声,效果比采用橡胶垫板减振的传统道岔显著。对于频率30Hz以上的振动,使用该类产品可降低噪声10～12dB。简要介绍其设计原理及在北京地铁10号线上的应用情况。 Turnout rail shock absorber is used in subway and light rail turnout orbit damping products, the structure of the form similar to ordinary shear rail shock absorber, without changing the original design of the switch by adding the product can Effectively reduce the vibration and noise generated by driving, the effect than the rubber pads used to reduce the traditional traditional turnouts significant. For the frequency of more than 30Hz vibration, the use of such products can reduce the noise 10 ~ 12dB. Brief introduction of its design principles and application in Beijing Metro Line 10.
