Static and Dynamic Analysis of Water Pump by MSC.Patran

This paper is a report for the safety analysis aimed at assessing the reliability and integrity of pressure retaining boundary of essential service water pump with complicated geometry using finite element method in MSC.Patran. The static analysis is investigated under five service loadings including the loads from OBE (operation basis earthquake) and SSE (safety shutdowan earthquake) (1). The natural frequencies and modal shapes of the pump are computed to check if the static equivalent load method can be used for the seismic analysis addressed in the future work. In addition, the stress analysis for the accessories of the pump, namely flanges and bolts, are also shown in the paper.
