다물체 모델링과 musclulo-tendon actuator를 이용한 Knee Joint 구속력의 불확실성 추정 연구

초록

The goal of this study is to expect to force applied at knee joint in the human body by using the Hill-type muscle model and The model, human body, is based on a musculoskeletal model of the human lower extremity in the sagittal plane. To perform this research human leg is modeled by multi-body modeling. This leg model has biarticular muscles, acting on two joints, and the muscles include some of the major muscles, such as hamstring, of the upper and lower limbs. To analysis the uncertainty of the applied forces that act on the knee joint, statistical distributions of human body, leg part, parameters are required and to obtain the parameter’s statistical characteristic of the part sample survey method is employed. Finally using the sensitivity information of the parameter the aim of this paper can be estimated.
