以渔子溪电站水轮机组为例，应用ARMD软件，通过改变镜板的转速、所受的轴向推力大小，得到推力轴承的油膜压力、油膜剪应力、油膜刚度和阻尼等的变化规律。结果表明推力轴承的油膜压力、油膜剪应力、油膜刚度和阻尼均随着轴向推力的增大而增大；随着镜板转速的增大而增大，在飞逸转速附近均急剧增大。

Taking the generating units in Yuzixi Hydropower Station as study case, the oil film property of thrust bearing is studied by using ARMD software. The change laws of pressure, moment, stiffness and damping of oil film under different rotation speeds and axial thrusts are calculated. The results show that the pressure, moment, stiffness and damping of oil film will increase with the increase of rotation speed and also increase with the increase of axial thrust, but will rapidly increase at the vicinity of runaway speed.
