摘要
基于一种双环形静压转台结构,采用格子Boltzmann方法(LBM)系统分析了转台内的油液流动,重点讨论了封油边间隙高度、入口速度及油液黏度对转台内油液流动的影响,利用压力分布曲线表征承载能力的情况。结果表明:3个参数对流线图中主涡的强烈程度、封油边径向速度分布及承载能力均有不同程度的影响;只有封油边间隙高度较小时,环形设置对转台的承载能力才有显著地提升;入口速度越大,油液黏度越小,中心凹槽与外侧凹槽的承载能力均有相应提升。
Based on a double ring hydrostatic turntable structure,the oil flow in the turntable is systematically analyzed by using lattice Boltzmann method(LBM).The effects of oil sealing edge clearance height,inlet velocity and oil viscosity on the oil flow in the turntable are discussed.The pressure distribution is used to describe the bearing capacity.The results show that the above three parameters have varying degrees of influence on the intensity of the main vortex,the radial velocity distribution of the sealing edge and the bearing capacity in the streamline diagram.Only when the clearance height of the sealing edge is small,the annular setting can significantly improve the bearing capacity of the turntable.The higher the inlet speed is,the smaller the oil viscosity is,and the bearing capacity of the central groove and the outer groove is improved accordingly.
