摘要
对船舶轴系扭振计算中最为主要的公式,平均指示压力、气体力所产生的干扰力矩、外阻尼等进行探讨和修正,经过实例计算与实际测量证明,完善了船舶轴系扭振计算,提高扭振计算的精度。其中,平均指示压力是计算简谐系数时的惟一参数,气体力所产生的干扰力矩是影响合成简谐系数计算的重要影响因素,外阻尼是计算动力放大系数的主要参数。
The formulas for calculating the mean indicated pressure, the resulting tangential forces of gas and mass excitations and the outer damping coefficients, are the most important calculating formulas for calculating shaft torsional vibration. In the paper these formulas ane modified in order to predigest them and to consummate the calculation accuracy. The mean indicated pressure is the only parameter for harmonics coefficient calculation. The resulting tangential forces of gas and mass excitations is one of important parameters for compound harmonics coefficient calculation.
