介绍了用传递矩阵法和剩余弯矩法相结合计算水轮机主轴临界转速的基本原理,并针对TI—59型计算器编制了程序框图。利用该程序可计算阶梯形主轴及等刚度轴的一阶和高阶临界转速,具有准确、易懂、方便的优点。
The basic principle of calculating the critical speed of turbine main shaft by using the transfer matrix method and the residual bending moment method is introduced. The block diagram of the TI-59 calculator is also compiled. The program can be used to calculate the first-order and high-order critical speeds of the trapezoidal and equidistant rigid shafts with the advantages of accuracy, simplicity and convenience.
