摘要

There are presented two methods used for an investigation of modal parameters, concretely natural frequencies and modal shapes of a significantly simplified model of compressor yard pipeline system in this article. The first one is an experimental method and uses experimental modal analysis for that purpose with using of system Pulse6. The second method is finite element method and was performed in software Solid Works. The pipeline was built in on one side and elastically supported on the other side. The modal parameters of a pipeline system were evaluated for two cases. First one where springs of pipeline support were not preloaded and second one where preload was applied.
