通过试验表明，在外力作用下，主轴在滑动或静压轴承中变形节点，不在轴瓦长度的中点，而是向悬伸端偏移。由此提出了滑动或静压支承主轴静刚度的计算方法。
Experiments show that under the action of external force, the main shaft deforms in the sliding or hydrostatic bearing, not at the midpoint of the length of the bearing bush, but shifts to the overhanging end. Therefore, the calculation method of static stiffness of sliding or hydrostatic support spindle is proposed.
