Attenuating vibration transmission from a Town Board Station (TBS) to the neighbor residential building using an optimum isolator: A case study

Town Board Stations (TBS) are usually located in residential areas. Pressure reduction through reducing valves in these stations generates considerable amounts of sound and vibrations. These mechanical waves have undesired effects on the equipment such as reducing the fatigue life of the gas ransmission line. On the other hand, propagation of these wave in the residential area, auses discomfort for the neighbors of these stations. In this paper, vibrations enerated in a TBS and transmitted to the residential building in the area are investigated through modeling and analysis. The aim is to study and propose a method for reducing vibration transmission from the TBS to residential buildings by using a numerical model. A vibration isolator is designed for this purpose with ptimum parameters and considering the practical limitations of the problem. The performance of the isolator is verified with the help of the developed FEmodel. Results show the effectiveness of the designed vibration isolator for the operating range of the TBS.
