PHASE ANALYAING METHOD AND SYSTEM OF BODY VIBRATION FOR DIESEL ENGINE

摘要

A method for analyzing a body vibration phase of a diesel engine is provided to input measurement and analysis data of body vibration into a computer. A method for analyzing a body vibration phase of a diesel engine comprises the steps of: inputting the rotating speed and sampling data of a generator from a rotating speed meter(S100); calculating the rotating number of the generator on the bases of inputted pulsation number(S110); judging whether the rotating number of the measured generator is equal to the predetermined rotating number(S120); rearranging data for high speed Fourier conversion and calculating rotating speed when the rotating number of the measured generator is equal to the predetermined rotating number(S130); carrying out the high speed Fourier conversion and calculating the intensity and phase of vibration(S140); and extracting the intensity and phase data for each degree(S150).
