Head Impact 성능 만족을 위한 Latch system 해석 기술에 대한 연구

Head impact performance is the one of the safety regulation in FMVSS 201, Domestic safety standard 88, ECE 21. The main contents of this regulation is that deceleration shall not exceed 80g continuously for more than 3 milliseconds to pass the test and interior compartment doors shall not open. Lately, interior compartment doors are designed on the center fascia of the crash pad to satisfy customer's convenience. So there are many problems that interior compartment door is open during the test in the last stage of the car development In this study we have tried to search optimum design spec of latch system and to set up the analysis technique to satisfy Head Impact regulation by using FEM simulation and DFSS technique in the early stage of car development.
