摘要
鉴于电动机主轴大部分为阶梯轴的情况,根据旋转梁的偏微分方程,推导出分布质量轴段的传递矩阵和求解临界转速的特征方程。以Micmsoft Fortran为计算工具,编制了相应的程序,求解并给出了具体的算例,验证了该方法的正确性。
According to the partial differential equations of the rotating beam, the transfer matrix of the mass-distributing shaft was derived because most of the motor rotating shaft was stepped shaft. And then characteristic equation to solve the critical speed can be derived. The calculation program had been worked out with Fortran. The experiment showed that the algorithm in this paper was effective and practicable.
