摘要
针对悬臂转子的圆盘一般具有较大宽度的特点,应用Lagrange方法推出了宽圆盘单元的单元方程并编制了相应的有限元计算程序.仿真计算表明:圆盘宽度对一阶临界转速有较大影响,不计圆盘宽度得到的结果比计入时偏大,但对三阶以上临界转速的影响不大.
In order to consider the influence of disk width on the calculated critical speeds of overhung rotors,this paper introduces a modification to the element equation of a wide disk by using Lagrange's method and the program for the finite element method (FEM) is developed.The simulation shows that the disk width has a notable influence on the firstorder critical speed but little effect on the thirdorder and above ones.
