Geometrical and Graphical Representations Analysis of Lissajous Figures in Rotor Dynamic System

This paper provides a broad review of the state of the art in Lissajous curve techniques, with particular regard to rotating machinery. Lissajous figure is a subject too wide-ranging to allow a comprehensive coverage of all of the areas associated with this field to be undertaken, and it is not the authors' intention to do so. However, a general overview of the broader issues of Lissajous curve is provided, it tells us about the phase difference between the two signals and the ratio of their frequencies, and several of the various methodologies are discussed. The experimental technique used Oscilloscopic with Rotor Rig; the display is usually a CRT or LCD panel which is laid out with both horizontal and vertical reference lines we can demonstrate the waveform images on an oscilloscope. The objective of this paper is to provide the reader with an insight into recent developments in the field of Lissajous curve, with particular regard to rotating machines. The subject of it in rotating machinery is vast, including the diagnosis of items such as rotating shafts, gears and pumps.
