选取船用柴油发电机组运行过程中可能出现的极端工况作为分析对象,通过轴系稳态扭转振动计算和瞬时扭转振动仿真,计算某型船用柴油发电机组轴系扭转振动固有频率、稳态运行扭转振动应力基础值和瞬间过负荷工况轴系扭转振动附加应力。综合考量、全面分析瞬间过负荷工况柴油发电机组轴系运行安全性,确保柴油发电机组全工况可靠供电。

[Abstract]
To ensure reliable power supply of diesel generator set at all working conditions, especially some extreme conditions, shaft torsional vibration calculation is carried out for the natural frequency, the steady-state basic stress and the additive stress at instantaneous overload condition for a marine diesel generator set the shaft, based on steady-state and instantaneous torsional vibration analysis of the shaft. Comprehensive study on the operational security of diesel generator set shaft at instantaneous overload condition can assure the reliable all-condition power supply.
