对高速旋转的机器,必须仔细进行动力计算,以保证不致发生破坏性振动。这种计算所需的轴承刚度值,通常必须用高价的实验或复杂的计算来获得。有一种简单的新方法,对精确度要求不高的研究项目,能给出轴承刚度的
For high-speed rotating machines, careful calculations of power must be made to ensure that no damaging vibrations will occur. Bearing stiffness values required for this calculation usually have to be obtained with expensive experiments or complicated calculations. There is a simple new method for less demanding research projects that gives the bearing stiffness
