FMH의 차체 재사용을 고려한 Restart 충돌 시뮬레이션 방법에 대한 연구

Recently it is highly requested that the interior compartment of a passenger vehicle must be satisfied with the FMVSS201U regulation, FMH head impact test. The FMH test must be conducted several times in developing stage of vehicle until the test result meet the requirement of the regulation. Usually, proto cars preparing for the verification test are limited and a proto car has to be used several times for the test changing the impact absorber. So even though the impact absorber be changed better, sometime the result of the next test would be poor. In this study, the restart simulation method is used for understanding the effect of the repeatable use of the testing car for FMH test.
