英文摘要	In this paper, fluid-structure interaction modeling of poppet fluid was presented, response of poppet under the action of step and periodic excitation signal was simulated, and dynamic characteristics of viscous force and hydraulic force on poppet surface were analyzed. The investigation indicates that poppet surface before valve port can be divided into jet impingement area and static pressure area under the action of submerged jet, and the dynamic characteristics of hydraulic force on these areas and axial vibration of poppet are closely related with length of jet impingement and poppet structure. Furthermore, for hydraulic force on jet impingement area, hydraulic force on static pressure area, and viscous force, if amplitude and phase have a reasonable configuration, axial vibration amplitude of poppet can decrease greatly. © Institution of Mechanical Engineers.
