An approach using active structural acoustic control
für 71.10€ kaufen ··· 9783844397222 ··· 10361119539 ··· A complete analysis of the structure-borne noise transmission paths of an automotive suspension assembly is presented. First, a fully-instrumented test bench consisting of a wheel/suspension/lower suspension A-arm assembly was de- signed in order to identify the vibro-acoustic transmission paths (up to 250 Hz) for white noise excitation of the wheel. Second, an analysis of the vibro-acoustics of the suspension is presented an overview of the Frequency Response Functions (FRF) is introduced and their respective modal behaviors are described. Frequency response function measurements between the excitation signal and each suspen- sion/chassis linkages are used to characterize the di®erent transmission paths that transmit energy through the chassis of the car. Finally, a synthesis of the major modal contributions of the suspension is drawn, with the objective of indicating which suspension transfer paths contribute the most to the structural forces trans- mitted to the chassis. Modal transmissibility factors (MTF) were calculated to pro- vide an overall classi¯cation of the modes to the vibration transmission through the individual suspension linkages and the orthogonal directions.
