摘　　要：应用有限元软件ANSYS分别对3种板条结构形式的水润滑橡胶轴承进行静态接触仿真分析,研究板条接触变形后形成的楔角、水囊以及接触压力对润滑性能的影响规律。结果表明:在相同载荷下,凸面型轴承垂向位移最大,平面型次之,凹面型最小;平面型橡胶轴承比凹面型橡胶轴承具有更好的润滑性能,更适合实际应用。Simulation analysis of static contact on three different stripe structures of water-lubricate rubber bearing was done with Ansys.The lubrication mechanism of rubber bearing and the effect of different stripe structures on lubricating property were researched including surface topography of the Bearing Strip after the contact deformation,wedge angle,water sac which appear and contact pressure after deformation.The result showed that in the condition of the same load,there is a maximum vertical displacement in the convex stripe bearing while the minimum displacement exists in the concave stripe bearing.Plane stripe bearing is more suitable for practical application due to its better lubricating property.
