전복안정성 평가방법의 적정성 연구

This paper presents a study of appropriateness for the roof strength evaluation method. Current roof strength test methods do not cover the real rollover accident trend because the test condition is quasi-static. The vehicle CAE model was developed using ADAMS in this paper. The model consists of A/B/C pillar, Roof-bows, Side Roof-rail and Body frame. The model was used to simulate quasi-static and dynamic roof crush test. The quasi-static roof crush test condition was followed IIHS"s test protocol. And the dynamic roof crush test condition was followed the paper "A Proposed Rollover and Comprehensive Rating System", which was released 2009 ESV Conference because the dynamic roof crush test protocol hasn"t been developed yet. The name of dynamic roof crush test equipment is Jordan Rollover System (JRS). L 27 orthogonal array is adopted for DOE (Design of Experiment). Also, the test results show which member affects roof crush performance and presents that dominant members are different between quasi-static and dynamic roof crush test.
