QBH indirect water cooling structure thermal deformation analysis method based on COMSOL

The invention relates to a thermal deformation analysis method of a QBH indirect water cooling structure based on COMSOL, and belongs to the technical field of finite element analysis methods of optical mechanical structures. According to the method, NX three-dimensional drawing software is utilized, a QBH indirect water-cooling structure three-dimensional model is established, a geometric model is imported through a CAD import module of COMSOL software, and finite element model establishment time is greatly saved; the deformation analysis method under the influence of the thermal stress of the QBH indirect water cooling structure is provided through a COMSOL'thermal expansion 'structural mechanics-solid heat transfer multi-physics field coupling interface; the extrusion deformation condition of thermal stress generated by different metal materials on the quartz end cap and the thermal stress change condition of the quartz end cap in a cooling water temperature rise state when the QBH indirect water-cooling s
