Abstract: Abstract According to the method of sensitivity analysis, responding factors of sealing performance on gate valve of thermal power (GVTP) are simplified. The relationship of sensitivity and displacement of sealing surface is expressed by mathematical equation. From 41 design parameters, it chooses 10 major global parameters to compare the degree of sensitivity and get the highest sensitivity parameters. The quantity of counting is reduced and the times of iteration are shortened obviously. Using the Monte-Carlo method, sampling points are reduced by 35 % and the maximum total deformation is reduced by 21 %. By using of optimized, the sealing performance of the GVTP is improved, the leaking on the sealing surface is restrained completely. The result of sensitivity analysis can provided reference in the optimized process in power system with high parameter.
