자동차 휠 베어링 설계 시 3축성형한계를 고려한 크랙 예측

In this study, orbital forming process, assembly method of automotive wheel bearing hub and inner ring, was analytically implemented using the STAMPACK™ that is based on explicit finite element method. CPU time significantly reduced beside implicit finite element method and STAMPACK™ analysis showed similar results with the test data. Additionally, It predicted crack and found solution plan using TFD(triaxiality fracture diagram).
