Structural strength analysis of high-pressureoil pump under fluid-solid coupling conditions

A high pressure oil pump has the advantages of compact structure, high working pressure, and it canstill maintain a high efficiency when it is working, so it is very important to analyze its structural strength. A high-pressure diesel monomer pump is the research object, it is using the finite element software Hypermesh to do thepretreatment of the finite element model, then using Fluent software to analysis the fluid finite element modelwhen it pumped oil to obtain the distribution of oil pressure in the process of pumping oil. And then it is usingAbaqus software to analyze the strength of the related components of the model through mapping oil pressure at thetime of the maximum oil pressure distribution to the model by the structure finite element interpolation, so it canobtain the stress distribution of each component. According to this coupling method to analyze the structuralstrength of high pressure oil pump, it provided the better guidance and reference for the design and optimization ofhigh pressure oil pump.
