3D 패턴드 타이어에 대한 정상 상태 롤링 해석 기법 적용

The steady state rolling analysis method in relation to tire analysis has been often used for the research of tire rolling performance because of the efficiency of computation time. But, this has a limit that meshes in the section have to be the same along the circumferential direction, so can not consider 3D pattern. That is, as above reason, this has been used for performance research in relation to only tire structure factors without 3D pattern until now. However, from now, it is possible to analyze in consideration of 3D pattern due to F.E. code development recently. So, in this study, we have examined the application of rolling performance research of 3D patterned tire using steady state rolling analysis implementing ABAQUS Release 6.6. We have analyzed the PRAT in relation to vehicle pull, cornering stiffness in relation to steering response, the footprint shape and F&M in the cornering state, and compared with test results.
