Dynamic response analysis of a table top compressor foundation

Abstract

Dynamic response analysis of a table top type foundation for a large centrifugal compressor destined for a plant in an earthquake endangered area has been carried out using FE computation model. The soil-structure interaction has been considered by including the subsoil body into the model. The foundation design has been optimized with respect to severe restrictions of vibration intensity. Both steady state and transient responses to forces due to unbalances have been computed. Seismic response has been computed using the linear response spectrum method.
