Active control of radiated noise and vibrations from an automobile fuel tank

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Neural Active Control for Vibrations and Noise Suppression

An adaptive vibration control system based on Diagonal Recurrent Neural Networks has been developed and experimentally verified on a rectangular flat aluminum panel with piezoelectric sensors and actuators applied on both surfaces. The objective was to reduce the structural vibrations induced by an electromechanical harmonic disturbance excitation in correspondence of the resonance frequencies ...

Radiated Noise from an Externally Blown Flap

Ground-borne vibrations and re-radiated noise in buildings from underground railways

A numerical model for ground-borne vibrations and re- radiated noise in buildings from underground railways

An efficient and modular numerical prediction model is presented to predict vibrations and re-radiated noise in buildings due to metro trains. The approach comprises of three weakly coupled problems: the dynamic vehicle-track-tunnel-soil interaction problem, the dynamic soil-structure interaction problem and the calculation of the acoustic response inside the rooms. The three-dimensional dynami...
