Abstract

This paper presents the biomechanical analysis and evaluation technology of musculoskeletal system by multi-body human dynamic model and 3-D motion capture data. First, medical image based geometric model and material properties of tissue were used to develop the human dynamic model and 3-D motion capture data based motion analysis techniques were develop to quantify the in-vivo joint kinematics, joint moment, joint force, and muscle force. Walking and push-up motion was investigated using the developed model. The present model and technologies would be useful to apply the biomechanical analysis and evaluation of human activities.

인체 근골격 시스템에 대한 다물체 동역학 모델을 이용한 동작중의 인체 내부의 생체역학 분석 및 평가 기술에 대하여 기술하였다. 의료영상과 사체실험 결과를 기본으로 하는 인체 다물체 동역학 모델과 3차원 동작분석 시스템을 이용한 인체 동작분석기술을 이용하여 생체내 발생하는 관절기구학, 관절모멘트 관절접촉력 및 근력을 예측하는 기술을 보행과 팔굽혀펴기 두 동작에 적용하였다. 본 연구에서 개발한 인체 다물체 동역학 모델링 기술과 3차원 동작분석기술은 다양한 동작을 수행하는 생체의 분석 및 평가 기술로 활용성이 높을 것으로 생각한다.
