The driving moment which used to be expressed, after some simplification, by step functions are now treated in strict accordance with the practical characteristics of the motors being used.

In this paper three dynamic mathematical models for the shaft-mounted silting system are suggested. Either the a.c. motor driven or the d.c. motor driven systems are investigated. The driving moment which used to be expressed, after some simplification, by step functions are now treated in strict accordance with the practical characteristics of the motors being used. The experimental curve in which the resilient peak torque is plotted against the torsional rigidity K_1 of the torsional buffer bar is found to be in good agreement with the theoretical curve. Both the numerical analysis and the experiment show that the use of a resilient buffer helps to reduce the peak torque considerably. Also in this article, we have solved the problem of the determination of the parameters of a tersional bar buffer by numerical method for constrained optimization.

本文建立了转炉全悬挂倾动系统的三个动力学数学模型。倾动系统被区分为交流电机拖动系统或直流电机拖动系统。驱动力矩不再象以往那样简化为阶跃函数,而是决定于所用电机的实际机械特性。弹性尖峰力矩对于扭力杆缓冲装置的扭转刚度K_1的实验曲线与理论曲线基本一致。实验和数值分析都表明弹性缓冲装置能够显著地降低尖峰力矩。通过约束优化的数值方法解决了扭力杆缓冲装置的参数设计。

This paper reduces a classic mode of two-point engagment and flexible transmission system to multi-masses torsional vibration system of two branches.The following velocity of all the lumped mass in this system has been carefully considered by the author (Different from those data [5]……available in this country Where only the following velocity of partial masses was considered.) The Second Kind of Lagrange Equations offer the motion equations of the system:[J]+[K]{q}={Q}With Cholesky Square Root Method and Jacobi Method we obtain the natural vibration Solution. The natural vibration solution gained by the methods mentioned above has been verified with the diffrence between the elements of [K]·and [J] reaching 10~(12) in this kind of system.By applying Filon Integration Folmla to Duhamel's Integral, we obtain the forced vibration solution of the same system, We emphatically discuss availability of these results.With the above methods, we calculate the torsonal vibration of the transmission system of 200-kilogram test converter (a modeling converter of the 250-ton converter). The calculated results are compared with the testing one of the same system. It is found that they quite agree with each other.These methods can easily be employed and realized with the ordinary small and medium-sized computer.

本文将典型的二点啮合柔性传动轴系归结为二分支的多质量扭振系统。作者对系统中每一个集中惯量所具有的牵连速度都作了考虑(已见资料[5]等仅考虑了部份惯量的牵连速度),用第二类Lagrange方程式推得了系统的运动方程式(组)[J]+[K]{q}={Q} 文章用Cholesky方法和Jacobi方法获得了系统的固有振动解,并用多种途径证实了甚至[K]与[J]矩阵元素之间相差达10~(12)的该类系统用上法得到的固有振动解的可靠性。文章还应用Filon积分公式于Dubamel积分获得了系统的强迫振动解。本文着重讨论了这些解的可靠性。按上述方法对200公斤试验转炉(250吨转炉模拟转炉)的传动系统的扭转振动进行了计算,计算结果与该转炉的试验结果相吻合。此计算方法可以在常用的中小型计算机上顺利地实现。

Based on some principal theories of control engineering, the mathematical expressions between the torsional rigidity of the torsional bar and the main dynamic characteristics of the Shaft-Mounted Tilting System in Converter are derived in this paper. These calculations and analyses are carried out for the reference model of a 300 Tonne Converter. This paper will provide the theorctical basis for the selection of the tor- sional rigidity of the Shaft-Mounted Tilting System in Converter.
