本程序适用于求解直串型初轧机主传动系统的多自由度扭振的频率、振型和各轴段扭矩。从轧机实际工艺情况出发,考虑系统阻尼和初条件、任意型激振力的作用。它不同于数值解程序,最后输出的是扭矩的解析解。本程序用 BASIC 编制,方便、实用,在 NORD—100计算机和“环宇”微型机上调试通过。计算结果与实测相符。 This program is suitable for solving the frequency, vibration mode and torsion torque of multi-degree-of-freedom torsional vibration of the main drive system of the tandem mill. Starting from the actual mill process conditions, consider the system damping and initial conditions, the role of any type of exciting force. It is different from the numerical solution program, the final output is the analytical solution of the torque. The procedures used in the preparation of BASIC, convenient and practical, in the NORD-100 computer and “Universal” micro-debugging through. The calculated results are in accordance with the measured ones.
