| Abstract: | Both analytical module of PDS(probabilistic design system) in ANSYS and the response surface method of probabilistic analysis were employed to calculate the reliability of designed spherical tank.The analytical results show that the reliability design can ensure structure reliability and economical efficiency as required,and sensitivity analysis in ANSYS can provide references for the reliability design. |
