| 摘要:为使轴系自由振动计算得到的固有频率更加接近实际情况，提出了一种有阻尼柴油机轴系扭转自由振动计算方法，将柴油机轴系中大阻尼部件的阻尼参数纳入到轴系扭转振动自由振动计算的考量范围。将该方法应用到某PC2﹣6柴油机试验台架扭振计算，计算结果与实测结果吻合较好，验证了该方法的可靠性和实用价值。 |

| Abstract:To make the shafting natural frequencies calculated with damping coefficient closer to the actual shafting resonance frequencies, a calculation method of free torsional vibration of damped diesel engine shafting was put forward, which brought damping factors of big damping parts from diesel engine shafting
into consideration. This method was applied to a PC2﹣6 diesel engine test bench torsional calculation, and the results coincided well with the test results, which verified the reliability and feasibility of this method. |
