| Abstract: | Based on the theory of dynamics and motion, the model for simulating the instantaneous angular speed in diesel engine is presented. The calculating software is developed with LabVIEW, the instantaneous angular speed is calculated and analyzed. The instantaneous angular speeds are also measured and analyzed in laboratory. By comparing the results of the measurement and the simulating calculation, the dynamic model is proved to be correct and faults can be diagnosed. Considering the influence of propeller, the applied conditions of the instantaneous angular speed method for fault diagnosis are discussed. |
