유한요소해석을 이용한 오일리스 베어링의 분말 압축 성형에 관한 시뮬레이션

초록

In this study, simulation on the powder compression forming of oilless bearing is performed and the analysis results are compared with the actual products. This study aims to examine the suitability of powder compression for bearing by using FEA(finite element analysis) before full-scale production. The lubrication state can be predicted by changing the coefficient of friction in order to get the optimal density gradient. Analysis for single and double action presses are performed and these results are compared with each other. State and process of optimal lubrication are proposed from the study result.
