Finite Element Modeling and Analysis of Composite Encapsulating Materials in Reactor Under Thermo-mechanical Coupling Conditions
摘要
Abstract
The design optimization and service life extension of composite encapsulated reactors are crucial,while their damage modes and failure mechanisms under thermo-mechanical coupling still need further in-depth research.Based on ABAQUS finite element software,the thermo-mechanical coupling analysis is carried out on glass fiber reinforced composite reactors.Firstly,the finite element geometric model is established according to the actual reactor structure.The reactor adopts axial and circumferential layered laying modes,and the ply angles of composite materials are set via discrete coordinate system.Combined with HASHIN failure criterion and thermo-mechanical coupling analysis step,the thermo-mechanical behaviors of the reactor are analyzed.The research results show that obvious thermal expansion appears in the middle area of the reactor under non-uniform temperature field,which easily causes fiber tensile failure.Restricted by end displacement constraints,fibers and matrix cannot deform freely,resulting in compressive failure.The research conclusions provide important theoretical basis for design optimization,failure prevention and service life improvement of composite encapsulated reactors.关键词
