扭振计算 meaning in English
torsional vibration calculation
Examples
- Calculation of man b & w 10l90mc diesel engine is taken as an example in the course of analysis and comparison and some relevant suggestions are made on its management
与扭振计算书的计算结果进行分析比较，证明了计算方法的正确性，并提出相应的管理建议。 - The of calculation methods of shipping shaft torsional vibration although have been already mature because of at a period of time inside , domestic and international many scholar that very grow proceeds to this with the related expert in - depth research
船舶轴系扭振计算的方法虽然已比较成熟，在相当长的一段时间内，国内外的许多学者和相关的专家对此进行了深入的研究。 - A open - close mathematic model is introduced into calculation of torsional vibration . results show : kurtosisness and high harmonic will increase when crankshaft have crack . 5 . cylinder score is also diagnosed by torsional vibration in this paper , when cylinder score occurring , the friction of piston will decrease the action of air pressure
本文借鉴了裂纹转子刚度的开闭模型，首次对含有变刚度单元的柴油机动力装置进行了扭振计算，结果表明柴油机曲轴有裂纹后，扭振的角位移和附加振动力矩的高谐次分量会增加，峭度值增加。 - Man b & w 10l90mc diesel engine is a new type of man diesel company and it has been used in large container vessel . in order to investigate into the characteristic of shaft torsional vibration when any single cylinder flames out and how that affects the main power propulsion system of a ship , the author puts forward a new way of calculation concerning the shaft torsional vibration when the mean indicated pressure of other cylinders remain unchanged
在此基础上，开发了新的船舶轴系扭转计算软件，并以manb & w公司近几年新推出的一种大功率多缸柴油机manb & w10l90mc型柴油机为例，分别进行了额定功率下和单缸熄火下的扭转计算，并提出单缸熄火时其他缸平均指示压力保持不变的轴系扭振计算方法。
