Abstract
The problem of vibration of the buildings and transformers in the urban substation has becoming more and more socially concerned. The urban substation and its associated building are taken as the research object. the vibration tests and modal shapes of the building and each floor slab were carried out. The transformer vibration and its noise were transmitted with obvious attenuation in the structural floor slab. The vibration transmission into the lower floor slab was higher than that of into the higher one. The further away from the transformer room, the vibration characteristics are weak, and the attenuation is no longer significant. At last, the finite element model was established for the urban substation. The transformer and floor slab vibration went through the simulated analysis and the consistent analysis results were obtained.
