英文摘要	Aiming at investigating the fluid-solid-dynamic behaviors of the liquid-end of high-pressure and high-flow-rate reciprocating pump in pure water medium, the dynamic characteristics of the suction and discharge valves of liquid-end based on AMESimhydraulic system simulation technology and the flow field distribution in the liquid-end based on FLUENT CFD technology are established. Three-dimensional finite element (FE) analyses on the strength of liquid-end manifold were carried out by the use of ANSYS commercial code. The AMESim simulation results show that the maximum impact velocity of the discharge valve is 0. 347m/s and the volumetric efficiency is 99.53%. Based on the CFD results, the effect of the configuration of flat valve on the vibration and noise behavior during the suction and discharge processes of the liquid-end manifold is discussed. The FE results suggest that the maximum stress in a value of 198 MPa occurs at the intersecting holes of the liquid-end manifold. The FE-based safety factor is 3. 21, which meets the fatigue strength requirements for important parts. © 2019 IEEE.
