【Abstract】 In this study,the three-dimensional finite element model of manual eccentric ball valve is built using ANSYS software. Then the seismic analysis is carried out. Not only the static analysis is carried out,but also the spectrum analysis and time-history analysis are carried out through selecting common typical earthquake wave. Through comparison,we find the three results are close,but the static method is conservative. According to the actual requirements,the calculation results are close among three methods. In the computation efficiency,the static analysis is better than the spectrum analysis and time-history analysis.更多还原
