Getzner provides mass-spring systems to reduce vibrations in metro rail system
Pune: Urban train operations generate vibrations and noise, which affect the people living and working in its surroundings. The mass-spring system from Getzner efficiently mitigates such vibrations and the secondary air-borne noise. Getzner’s mass-spring system is installed in over forty cities worldwide – amongst them are the Indian cities of Bangalore, Delhi, Lucknow and Mumbai. T he train operations generate vibration energy at the track superstructure because of high dynamic loads. This vibration energy propagates through the ground and once it reaches a building, depending on the dynamic characteristics of the building, it can be perceived as vibrations or can be heard as secondary air-borne noise, adversely impacting the lives of people in the vicinity of the metro corridor. “The effect of vibration and noise is different in every building depending on it structural characteristics. That is why we aim to control the vibrations at the source itself – the met...
