Nonlinear Characteristic of Clamp Loosing in Aero-Engine Pipeline System

نویسندگان

چکیده

Long service time and excessive vibration of aero-engine will cause failure clamps, which usually fix pipelines on the outside an aero-engine. In this paper, nonlinear characteristics caused by loosening clamps in pipeline are determined. According to real parameters clamp-pipeline test rig, clamp is simplified into a spring-damping. Thus, model based cubic stiffness established. The multi-scale method used obtain analytical solution model. Based data, system identified, then obtained. Finally, using transmissibility method, influence severity

Study on a Pipeline Tension Detection Method for Aero-pipeline Spraying System in Paddy Field

Aero-Pipeline Spraying System is a special ultra-working-width precision pesticide sprayer, which can broaden working scope, improve working efficiency, precisely transfer feed liquid to farm field that need to be sprayed, spray pesticides to crops in a very close range, and then improve working precision and reduce the losses of liquid materials such as pesticides. During the ultra-working-wid...

The Chaotic Prediction for Aero-Engine Performance Parameters Based on Nonlinear PLS Regression

The prediction of the aero-engine performance parameters is very important for aero-engine condition monitoring and fault diagnosis. In this paper, the chaotic phase space of engine exhaust temperature EGT time series which come from actual air-borne ACARS data is reconstructed through selecting some suitable nearby points. The partial least square PLS based on the cubic spline function or the ...
