Abstract
According to the real structure and work condition of a high-flow gas pressure control valve used in recycling generating electricity project, a multidisciplinary design optimization (MDO) model is set up. Taking the structure and flow field analysis results as designing criterion, the MDO framework is put forward, which realizing the integration of multidisciplinary and two physical fields of control valve. To ensure that the gas transmission capacity which is the design prerequisite, the optimization takes reducing noise of control valve as system goal, while the valve wall thickness and flow velocity are decreased. And the Reynolds number, stress intensity and body total weight are also meet requirements. From the standpoint of fluid and structure, to realize MDO is of great practical significance for advancing research level of high-flow control valves.
