Abstract Aiming at the fluid-structure interaction of the control valve-pipeline-fluid system, a system simulation model is built with consideration of a valve positioner. The predictor-corrector method and the fluid-structure interaction finite element method are given respectively for solving response of the valve core-stem system and the valve-pipeline-fluid system. The vibration response of the system is analyzed by ANSYS software under the conditions of fixed and varying opening as well as flow-opening and flow-shutting. The results show that the pipeline and flow direction have great influence on the displacement of the valve core-stem system and the fluid unbalanced force on the valve core.
