Abstract : the simulated calculation and analysis of the fluctuation of the instantaneous speed of a diesel engine are presented. the important factors, influencing the measurement precision of the instantaneous speed, are discussed. the correct measurement method is presented. the instantaneous speeds of diesel engine are measured and processed in a laboratory condition. compared the simulated instantaneous speed with the measured instantaneous speed, the simulated result is correspondence with the measured result. the characteristic parameters and the criteria of the instantaneous speed for detecting the leakage of valves in diesel engine are provided, and diagnosis accuracy is confirmed on 4120sg diesel engine
文摘:對瞬時轉速波動進行了模擬分析計算；實測了發動機的瞬時轉速；對比了實測與模擬計算的瞬時轉速波形，兩者相當一致；討論了影響瞬時轉速測量精度的關鍵因素；提出利用瞬時轉速進行故障診斷的特徵參數及判據，並在診斷4120sg型柴油機氣門漏氣故障中得到證實 -
