BRAKE VIBRATION AND NOISE: REVIEWS, COMMENTS, AND PROPOSED CONSIDERATIONS

AukmIke b&e noise end vibr&n conbot have become hcteasi~ impMad for the tmpmvemenf of vehicle quietness and passenger comhd. Studies of tk pmbtem can be traced back os eo@ do the mid495ils. M pmqess has been main& confineo’ to fhe exptawtkw of mechanisms and the identbic~on of the sources of brake noke and vfbr&n. Mmy aspects of tk problem still remain unsolved becase of the comptexw of the pmblem itself This paper presents a comprehensive review ofprevious research on brake noise and vibration. The pti studies an tk sources and contdbutiwrs of drum and disc brake noise and wf~rafion, cn fhe methods and mechanicoi models used in experimentd, numeric&l and theoretical investigations. and on the mated& for brake friction and danping applications are summarized and dtscussed Tk opihtof~s end suggestions of the &hots we presented with emphases on the computer models with @mmic friction considerations end on the potenti&J appfication of advanced sbucturd Compo.9?~.
