摘要：
Urban rapid railway is one of the most popular transportation methods these days. It is equipped with large-capacity air compressors since it uses pneumatic pressure to supply power for braking and for opening and closing doors. Passengers tend to complain about vibration and noise from the air compressor. In this study, vibration reduction of air compressor was achieved by acquiring exact complex dynamic stiffness of the mounting rubber and optimizing the shape of it. Target stiffness values of the rubber was obtained from multi-body dynamics simulation of the air compressor-mounting system. Complex elastic modulus of the rubber mount was derived through EMA and Gent's method and verified by finite element method. Through parametric study of mounting rubber, an optimal shape of mounting rubber was derived and produced. Lastly, the proposed value was verified by experiments comparing with baseline value.
