大型透平压缩机组的转子系统是齿轮耦合轴系,工程上常用折合法或扭转耦合对这类机组进行扭振分析.通过数值计算将这两种方法与弯扭耦合计算方法进行了比较与分析,结果表明,目前工程中广泛使用的折合法或扭转耦合算法不能完全反映该类机组的扭转动力学特性,存在缺陷.为了使机组避免一切有害的扭转振动,在进行机组扭振分析时,必须考虑机组转子横向振动对扭转振动的影响,应用弯扭耦合振动理论进行系统分析.
- Abstract:
-
The rotor system of large turbine compressor units is gear-coupled shafting, and torsional vibration analysis is commonly used in engineering to carry out torsional vibration analysis on such units. These two methods are compared and analyzed with the bending and torsion coupling calculation method through numerical calculation, and the results show that the folding or torsional coupling algorithms widely used in engineering cannot fully reflect the torsional dynamic characteristics of this type of unit, and there are defects. In order to avoid all harmful torsional vibration of the unit, the influence of the transverse vibration of the rotor of the unit on the torsional vibration must be considered when the torsional vibration analysis of the unit is carried out, and the bending and torsional coupling vibration theory is applied for system analysis.
