Powertrain mounting system optimization to improve vibration behavior for EF7 engine

Improvement and optimization of the Powertrain mounting system are one of the ways to improve the performance NVH cars. The study aims to find the optimal stiffness coefficients for each mount in three directions. The natural frequencies of the system remain steady and stay away from the excitation frequencies, so that the system does not a resonance. It was also, using the decoupling vibration...

Learning Shape for Jet Engine Novelty Detection

Application of a neural network approach to data exploration and the generation of a model of system normality is described for use in novelty detection of vibration characteristics of a modern jet engine. The analysis of the shape of engine vibration signatures is shown to improve upon existing methods of engine vibration testing, in which engine vibrations are conventionally compared with a f...

Novelty detection in jet engine vibration spectra

This paper presents a principled method for detecting “abnormal” content in vibration spectra obtained from rotating machinery. We illustrate the use of the method in detecting abnormality in jet engine vibration spectra corresponding to unforeseen engine events. We take a novelty detection approach, in which a model of normality is constructed from the typically large numbers of examples of “n...

Estimator design in jet engine applications

Jet engines are nonlinear dynamical systems for which an exact mathematical model cannot be used for estimator design, because it is either not available or so complex that it does not fit the necessary assumptions. Thus, classical analytical tools for studying standard system properties like observability, which is very important in estimator design, cannot be directly applied. Generally, for ...

Bifurcation Stabilization withApplications in Jet Engine Control

Local output feedback stabilization with smooth nonlinear controllers is studied for parameterized nonlinear systems of which the linearized system possesses multiple pairs of imaginary eigen-values, and the bifurcated solution is unstable at the critical value of the parameter. Necessary and suucient conditions are sought for stabilization of such nonlinear bifurcated systems based on the proj...
