500t渔政船双机并车轴系扭振计算研究

Torsion vibration research of twin-engine incorporation propulsion shafting of 500t fishery administration ship

建立了500t渔政船双机并车系统当量模型,分析了其振动计算的特点;给出了双机并车轴系考虑柴油机各缸激励、两柴油机之间的相位角及各缸负荷不均性情况下的响应计算的方程,并计算了系统第1质量振幅和和最大轴段的应力.详细分析了两台柴油机相位角和气缸负荷不均匀性对系统振动特性的影响.

Establishing the model of the twin-engine incorporation system of 500t fishery administration ship, this paper analyzed the properties of vibration calculation, gives the equation under different conditions. The amplitude of vibration and the stress of maximum shaft part are calculated The influences on the vibration property of the system caused by phase angle of two diesel engines and heterogeneity of cylinder load are analyzed in detail.
