为研究水润滑轴承板条结构对其润滑性能的影响规律,利用有限元软件ADINA建立2D轴承底部中心板条的流固耦合模型,得到水膜压力分布,板条的综合位移和垂向位移分布,分析凹面型、平面型和凸面型板条以及橡胶厚度对水膜压力分布和板面变形的影响规律.研究表明:平面型和凹面型板条能够促进轴承形成流体动压润滑,凸面型板条减少水膜的承压区,不利于形成流体动压润滑;增加橡胶厚度,会降低水膜压力分布,增大橡胶的变形,从而降低了轴承的承载能力.
In order to study the influence law of water lubrication bearing slab structure on its lubrication performance, the finite element software ADINA was used to establish the fluid-solid coupling model of the bottom center slab of 2D bearing, and the water film pressure distribution, the comprehensive displacement and the vertical displacement distribution The effects of concave, flat and convex slats and rubber thickness on the pressure distribution and the deformation of the water film were analyzed.The results show that the plain and concave slats can promote the hydrodynamic lubrication of the bearing, Article to reduce the water pressure bearing zone is not conducive to the formation of hydrodynamic lubrication; increase the rubber thickness, will reduce the pressure distribution of the water film, increasing the deformation of rubber, thereby reducing the bearing capacity.
