借助ANSYS多物理场求解器的流固耦合功能对六沟槽水润滑橡胶合金轴承进行2D数值模拟,得到了水润滑橡胶合金轴承润滑膜内的压力分布、速度分布及橡胶轴瓦的弹性变形状况,进而分析了水润滑橡胶合金轴承的润滑性能。结果表明:在载荷较大及中高速工况下,橡胶轴瓦的弹性变形会显著影响水膜膜厚分布及水润滑轴承的润滑性能。
With the aid of the fluid-solid coupling function of ANSYS multiphysics solver, the 2D numerical simulation of six-groove water-lubricated rubber alloy bearings was carried out. The pressure distribution, velocity distribution and elastic deformation of the rubber bearing were obtained. Then the lubrication performance of water lubricated rubber alloy bearings is analyzed. The results show that under the condition of large load and medium-high speed, the elastic deformation of the rubber bearing bush will significantly affect the film thickness distribution and lubrication performance of water-lubricated bearings.
