Research on optimization design of rigid-flexible heterogeneous water-lubricated bearing composite materials
英文摘要：Aiming at the problem of limited mechanical properties caused by the single structure of the traditional water-lubricated bearing lining material, this paper studies a rigid-flexible heterogeneous composite biomimetic material. Bearing lining material for better mechanical properties; Because the composite bionic material has structural symmetry, the finite element analysis software Abaqus is used to simulate a volume element in the entire structure. The load-bearing properties of the structural units without fibers and those with fibers were compared and analyzed, and the effects of different fiber helix angles and fiber radii on the load-bearing properties of the material under the same fiber structure were obtained, and the optimal rigid-flex two-phase ratio was obtained. The research results show that the flexible matrix can support and protect the fiber structure, and the fiber helix angle and fiber radius need to be selected according to the performance requirements of the material. In order to have the best mechanical performance of the volume element, the optimal rigid-flex two-phase ratio of the volume element needs to be selected. In the research of this paper, under the same load condition, the mechanical properties of the volume unit are optimal when the fiber helix angle is 30°and the fiber radius is 0.6 mm. The research conclusion shows that the fiber structure composite with rigid-flexible phase has better mechanical properties than traditional water-lubricated bearing materials.
