타이어 성능 해석 자동화 및 최적화 프로세스 개발에 관한 연구

Tires should be satisfied various performances such as R&H, NVH, traction, and etc. To design tires considering these performances, we applied a multi-objective optimization method using metamodel to tires design and a finite element analysis to predict tire’s performances. However, building metamodel requires many repeatedly jobs for FEA in tire design optimization. In this study, to overcome these problems, we develped the FEA automation and design optimization process for tire design using commercial software Isight and the in-house code, and applied the process to a shape design optimization of tire contour to decrease tire`s rolling resistance to verify effects of the process from results of processing time.
