- 摘要:
- 针对传统水润滑轴承内衬材料结构单一导致的力学性能受限问题，研究一种刚柔异相复合仿生材料。该材料的基体为柔性材料，中间镶嵌刚性纤维，将其作为水润滑轴承内衬材料，以获得更好的力学性能。由于复合仿生材料具有结构对称性，因此采用有限元分析软件Abaqus对整个结构中一个体积单元进行仿真计算。对比分析无纤维和有纤维的体积单元的承载性能，以及同一个纤维结构下，不同纤维螺旋角度和纤维半径对材料承载性能的影响，得到最佳的刚柔两相比例。研究结果表明，柔性基体对于纤维结构具有支撑保护作用，纤维螺旋角度大小和纤维半径需要根据材料的性能要求进行选择。为了体积单元的力学性能表现最好，需要选择最优体积单元刚柔两相比例。同一载荷条件下，纤维螺旋角度30°、纤维半径0.6 mm的体积单元力学性能最优。研究结果表明，刚柔异相的纤维结构复合材料相较于传统的水润滑轴承材料具有更优秀的力学性能。
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.
