Simulation Analysis of Influence of Common Stiffeners on Stiffness of Ball Valves
The integral finite element model of the hydropower ball valve and the separate finite element model of the valve are established respectively by using the integral analysis method and the individual analysis method,and the results of the two methods are compared and analyzed.The finite element models of four kinds of rib plate styles of cross target ring,cross-shaped,川-shaped and 井-shaped are established by individual analysis method,and the effects of four common rib plate styles on valve stiffness are studied.The results show that the cross target annular rib plate has the most significant effect on increasing the valve stiffness,and the individual analysis method is efficient and the analysis conclusion is reliable.
