Description

technical field [0001] The invention relates to the technical field of coupling analysis of a flow field, a solid field and a temperature field, and in particular to a calculation method for two-way heat-fluid-solid coupling of a water-lubricated rubber bearing. Background technique [0002] With the gradual promotion of the application of sliding bearings, water-lubricated rubber bearings, as an important type of its development, have changed the traditional thinking that metal structures are used to form friction pairs in mechanical transmission systems, not only saving a lot of crude oil and precious metal materials, Moreover, the structure of the bearing shaft system is greatly simplified to avoid serious pollution of the water environment due to oil leakage. [0003] With the increasing shortage of oil and other energy sources, and under the background of advocating resource conservation and environmental friendliness, the use of clean energy has been paid more and more...
