[진동 소음부문] 마찰로 인한 디스크 브레이크의 유한요소 열탄성 불안정성 해석 = Finite Element Analysis of Frictionally Excited Thermoelastic Instability in Disk Brakes

다국어 초록 (Multilingual Abstract)

A finite element analysis is performed to investigate frictionally excited thermoelastic instability in automotive disk brakes. This instability leads to the localized high temperature contact regions such as hot spots in the automotive brake. It is assumed that linear perturbations on the constant speed solution vary sinusoidally in the circumferential direction and grow exponentially in time. This assumption in the themoelastic and heat conduction equations leads to a linear eigenvalue problem for the exponential growth rate for each wave number. The computational results are compared with an analytical solution for a layer sliding between two planes. The present method gives goods estimates for the critical rotational speed. Also. the effects of friction (pad) material properties on the critical characteristics are investigated.
