Effect of bearing speed on oil film stiffness of journal bearings

Effect of bearing speed on oil film stiffness of journal bearings

Answer:

The shaft and bearings are in direct contact. Is there an oil film at this time?! It is true that the eccentricity decreases and the stiffness decreases. But in the front, it depends.
Of course, the faster the turn, the greater the impact!
The general conclusion is that the higher the rotational speed, the greater the stiffness, the higher the oil pressure and the greater the stiffness. But not the greater the speed and oil pressure, because it will bring power consumption, temperature rise and stability of a series of problems
