Surface Temperature in Sliding Systems Using the FFT Finite Element Analysis

FFT-FEM을 이용한 윤활 기구에서 표면온도에 관한 연구

Finite element equations by using fast Fourier transformation were formulated for studying temperatures resulting from frictional heating in sliding systems. The equations include the effect of velocity of moving components. The program developed by using FFT-FEM that combines Fourier transform techniques and the finite element method, was applied to the sliding bearing system. Numerical prediction obtained by FFT-FEM was in an excellent agreement of experimental temperature measurements.
