本文用动刚度法导出各种支承型式的单盘等截面、无重轴转子的各个基本频率方程。经过对各主要参数的无固次化处理及计算后,得出能供实际使用的临界转速计算图线用此图线能快而准的求得各式转子的临界转速。
In this paper, the dynamic rigidity method is used to derive the single disk cross sections of various bearing types without the basic frequency equations of the heavy-shaft rotors. After the main parameters of the non-solidified and calculated, come to practical use of the critical speed calculation diagram with this diagram can be quickly and accurately obtain the critical speed of various types of rotor.
