摘要:本文针对S385型柴油机装车后,出现某一转速下的共振问题,设计了七种发动机平衡方案,并就各种平衡方案,在台架试验状态下进行了振动测量及对各点各方向的振动功率谱分析,合理地解决了振动问题。

Abstract: For resonance phenomenon at a
speed while S385 diesel engine is installed on vehicle,the paper designs seven
kinds of plan for balancing engine.On the basis of the plan,vibration
measurement and power chart analysis are carried out,and vibration to vehicle
is settled reasonably.
Keywords: Diesel Engine;Engine
Balance;Vibration Measurement;Vibration Analysis
