ABSTRACT

This paper introduces the load combination, criteria and methods of evaluation for seismic analysis, and verifies the seismic performance of the nuclear safety-Related butterfly valve by the ANSYS module of workbench. It has not only verified the structural integrity of the valve, but also verified and optimized the weak area of the valve at the design stage based on seismic analysis. It reduces the enterprise cost and shortens the product development cycle through the method of seismic analysis.

Keywords:Workbench, Seismic Analysis, Nuclear Safety-Related Butterfly Valve, Verify
