内燃机气体激振力矩相位特性与应用研究

Study And Application On Driving Torque Of Internal Combustion Engine

研究了内燃机气体激振力矩单谐次分量相位波动规律,及其对曲轴扭振相位特性的影响.说明了进行扭振计算时考虑激振力矩相位的必要性,进一步完善了利用单谐次扭振相位诊断故障缸方法的理论.

Fluctuation of phase of single harmonic drivingtorque is studied, and the relationship between phase ofsingle crankshaft harmonic torsion vibration and that ofcorresponding harmonic driving torque is described.When torsion vibration is calculating, the phase ofdriving torque must be taken into account. The approachusing phase of crankshall harmonic torsion vibration todiagnose the individual cylinder fault is developedfurther.
