摘　　要：在介绍船舶轴系扭振及应力计算方法的基础上,对某船厂生产的19 900 t化学品船进行了频率、共振转速等参数的计算。并对该船采用非接触的频率计数法进行扭振测量,通过计算机软件对测量结果分析得出了该船的转速禁区。完成了对该船的扭振校核。On the basis of introduction of the ship shafting torsional vibration and stress calculation method, to 19 900 tons chemical boat of a shipyard production, its frequency, resonance rotational speed and other parameters were calculated. The ship＇s torsional vibration measurement adoptednon-contact frequency counting method, and by computer software analysing measurement results, the ship＇s speed restricted range was got. The ship＇s torsional vibration checking was completed.
