众所周知,用能量法计算一阶临界转速具有足够的精度。其计算式为:口。I=(1)可以用其它与外力无关的参数来代替。 一设轴上有n个集中质量,其中第i个质量处。静挠度y;为: y;=过:gas:+m:ga;2+…+mogaon艺m iy式中mi—轴上集中质量 yi—其静挠度 y;是轴在重力作用下的响应。我们知
As we all know, using the energy method to calculate the first order critical speed has enough accuracy. The formula is: mouth. I = (1) can be replaced by other parameters that have nothing to do with the external force. A set of axes have n concentrated quality, of which the first i quality.
