对振动台上的液体静压轴承装置进行研究,对其相关结构进行数值模拟及优化设计。在理论分析过程中,首先建立了油膜及压力场分布的数学模型,在提出了一系列假设的前提下,得到了油膜间隙中液体流动的控制方程即简化的纳维尔-斯托克斯方程及边界条件;然后采用有限元分析软件ANSYS对油膜的流场进行了计算、流体力学数值模拟以及优化设计,解出油膜的压力分布、速度分布、承载能力、流量和最优解。以数值模拟分析为基础,重点进行了试验研究以及相关问题的分析。运用计算得出的最优解,进行了一系列试验。从得到的测试数据中,分析了各种参数对油膜性能的影响规律。
Hydrostatic bearing units on the vibrating table are studied, and their related structures are numerically simulated and optimized. In the process of theoretical analysis, the mathematical model of the distribution of oil film and pressure field was first established. Under the premise of a series of assumptions, the governing equation of liquid flow in the oil film gap was obtained and the simplified Navier-Stokes equation Then the finite element analysis software ANSYS was used to calculate the flow field and the hydrodynamic numerical simulation as well as the optimization design to solve the pressure distribution, velocity distribution, bearing capacity, flow rate and optimal solution of the oil film. Based on the numerical simulation analysis, the emphases are put on the experimental research and the analysis of related problems. Using the calculated optimal solution, a series of experiments were conducted. From the test data obtained, the influence of various parameters on the performance of oil film was analyzed.
