    摘要:

    滑靴副作为斜盘式轴向柱塞泵的主要摩擦副之一,长期工作于高速、高压、高温等一些复杂极端环境中.本文建立了滑靴副中流场的基本控制方程,构建了滑靴副多物理场耦合的有限元模型,通过CFD技术对滑靴副流场进行模拟分析,并在此基础上对滑靴副流-固-热多物理场耦合进行仿真,得到不同工况下油液的压力场和速度场的变化规律以及流体的压力和温度对滑靴副的总变形量、应力的影响.结果表明,随着工作压力增大,油液在阻尼管路中压力损失增加,油腔内涡旋个数及尺寸增大.除此之外还发现滑靴副变形量和最大应力对油液温度较为敏感.本文工作为滑靴副的结构设计提供了一定的技术支持,并且对于提高滑靴副的整体性能有着重要的意义.

    Abstract:

    As one of the main frictional subsets of swash plate axial piston pumps, the slipper pair mainly work in complex and extreme environments. In this paper, basic governing equations of flow field in the slipper pair are established, and a finite element model of the slipper pair is constructed. After that, the flow field is simulated by CFD, and multi-field coupling of the slipper pair is analyzed. The changes in pressure and velocity fields of the oil under different working conditions and the effects of fluid pressure and temperature on the total deformation of the slipper pair are obtained. The results show that as working pressure increases, the pressure loss of oil in the damping line increases, and the number and size of vortices in the oil cavity increase. In addition, it is also found that the oil temperature has a greater influence on deformation of the slipper pair. The current work provides some technical support for design of the slipper pair, which is of great significance for improving overall performance of the slipper pair.
