作者：李小燕首钢工学院

A new method is proposed to analyze the bearing properties of the preloaded oil pad in different compensation method when the hydrostatic turntable *** equation and Reynolds equation are coupled and solved in this *** show that the bearing properties of the preloaded oil pad will be significantly reduced when *** load carrying capacity even decreases by 42% at maximum tilt *** the heat produced in the lubricant film by friction also has a significant impact on the bearing properties of the preloaded oil pad.
