- 103 Extraction Method of Failure Component on Vibration and Acoustic Signals Generated by a Reciprocal Engine Based on Cross Correlation of Close Two Point Signals and Characteristic of Paralleled Auto Regressive Model with Extra Input
抄録
The failure diagnosis by vibration and acoustic signals on reciprocal engine is more difficult than independent mechanical elements, because almost reciprocal engine is composed of great number of structural bodies and mechanical elements. Reciprocal engine find it hard to identif' of failure elements to exist a number of noise sources within the engine. This paper experimentally examines the possibility of diagnose failure conditions about a four stroke twin cylinder reciprocal engine based on generated vibration and acoustic signals measured by two accelerometers and two microphones. Artificially assumed failure condition in the four stroke twin cylinder reciprocal glow engine is concerning push rod driven rocker arm and intake and exhaust valves. Identification of above the failure conditions has been carried out based on cross correlation function of close two points signals and paralleled ARX model (Auto Regressive with Extra Input) at diagnosed location within the engine. It is possible to diagnose above failure condition by the proposal SN ratio improvement method.
