一関節筋と二関節筋の協調による四肢の力出力分布特性: 関節トルクを利用した力出力分布の計測手法

摘要

Until now, output force distribution characteristics in human limbs have been discussed based on joint torque. Furthermore, a measurement method of joint torque was prescribed in detail, and measured value is shown as database to the public. However, in another precedent study, the relationship between output force distribution and muscular strength in human limbs was demonstrated under the theoretical back ground of the coordination of mono-articular muscles and bi-articular muscles, and the relationship between output force distribution and joint torque was made clear more. In this study, under the theoretical back ground of the coordination of mono-articular muscles and bi-articular muscles, new simple measuring method of output force distribution characteristics using joint torque was proposed and its validity was discussed.%近年，ヒトの身体寸法や関節可動域といった幾何学的な特性や四肢の関節トルクなどが，人体寸法・形状データべ－スや人体寸法データベース，人間特性データベースなどとして一般に公開されている．これらのデータを用いて，コンピュータマネキンあるいはデジタルヒューマンによって，コンピュータ上でヒトと環境や物体との干渉，四肢の可動域や力出力など推定することが可能となり，製品設計や作業の評価に用いられつつある．
