본 논문에서는 작은 여성 승객의 충돌해석을 위한 유한요소 모델링에 대하여 Part I 의 분절된 강체 모델에 이어 소개하고 있다. 추가로 모델링 된 상세한 팔, 다리 및 내부 요소들이 분절된 강체 모델에 합체되어 충돌 상해 즉 골절 또는 탈골 등을 예측하게 된다. 이러한 사지 및 내부 요소들의 거동 특성은 확보된 사체 실험 결과와 비교, 검증하였다. 따라서 본 논문에서 제안하고 있는 작은 여성 인체 모델은 충돌 상해 기구학의 조사 및 현존하는 충돌 더미의 생체 충실도를 보완하는데 활용될 수 있다.

It is necessary to have a dummy that describes the anthropometry of a victim with accuracy. This study presents three scaled side impact dummies constructed for the use of MADYMO. They represent five, fifty and ninety-five percentile Korean males ranged from the age of 25 through 39. Thirty-five anthropometric data were used to scale input files required for MADYSCALE. Geometries, inertia, joints and other parameters for dummies were scaled based on the configurations of EuroSID-1. This study proposes the lateral impact response requirements for head, thorax and pelvis of Korean side impact dummies. A lateral drop impact test was conducted for the head at the height of 200 mm. Lateral pendulum impact tests were also carried out for thorax and pelvis at three specific impact velocities. All these test results were obtained from simulation based on MADYMO. All the procedures of the three tests followed the requirement of ISO/TR 9790.

A new dummy has improved biofidelity from Fair to Good compare with EuroSID2re which is currently used for regulation tests and NCAP tests. Some instrumentation of each body region has been changed to measure the assessment of injury risk. The objective of this study is to find out the injury characteristic of each dummy and to calculate the relation between external force and injury for each dummy with pendulum tests. Finally, this study suggests the optimized external force to meet consumer tests. A new dummy named WorldSID for side impact will be introduced into EuroNCAP tests after 2015. Korea government is also planning to adopt WorldSID at KNCAP tests from 2017 and Global Technical Regulation (GTR) will also adopt WorldSID to oblique side pole crash.

NCAP(New Car Assessment Program) makes vehicle manufacturer improve safety performance through free competition and customers guarantee vehicle selection by providing information of vehicle safety. That's why it is important not only to meet the regulation, but also to cope with NCAP. EuroNCAP(European New Car Assessment Program) side tests have conducted by using Progressive MDB and Euro SID II in order to reproduce crash test between two vehicles over 10 years. However various researches report that Progressive MDB and Euro SID II do not reflect evolving vehicle design, impact performance and biofidelity of human. Therefore EuroNCAP has the plan to conduct AE-MDB side crash test using WorldSID which is more evolved from 2015 by replacing Progressive MDB and EuroSID II. Automobile manufacturers need to develop safety performance for new test closely. This paper is to find test set-up parameters which affect into dummy injury instead of restraint system and to research on its tendency. It is processed with mini and small car to know influence as changing vehicle size and also analyzed by DFSS(Design for six sigma) which is one of optimization tools. DFSS is vaildated by simulating CAE with L18 orthogonal array of 6 control factors adjustable as EuroNCAP requirement.
