자동차용 클러치의 저더 발생시 열탄성 불안정성에 관한 연구

초록

In this paper, it was studied the thermoelastic instability of automotive clutch under juddering. In order to study transient thermal behavior of the automotive clutch, the experimental method and the finite element analysis were utilized. For the experimental study, a clutch dynamometer was used and instability conditions were found through the experiments. Temperature and displacement distribution were obtained in the three-dimensional nonaxisymetric model using FFT-FEM method that combined Fast-Fourier Transform and the Finite Element Method.
