| 本文围绕着数字人体多体系统层圈块体的运动学特征,开展了数字人体多体系统运动的层圈块体上固定点的速度和加速度,层圈块体上动点的速度和加速度,数字人体多体系统的坐标、自由度和约束方程,数字人体多体系统的偏速度和偏角速度和数字人体多体系统的变换矩阵与导数研究,为建立数字人体多体系统层圈块体的运动学模型提供理论依据和建模基础。 |
| 英文摘要: |
| Surrounding on the kinematics character of layer-circle block-body of multi-body system of digital human body, we developed to study the velocity and acceleration of fixed point on layer-circle block-body of multi-body system movement of digital human body, the velocity and acceleration of move point on layer-circle block-body, coordinate, freedom degree and restriction equation of multi-body system of digital human body, partial velocity and partial angle velocity of multi-body system of digital human body, transform matrix and derivative of multi-body system of digital human body. It provided a theoretical gist and model construction basis for establishing the kinematics model of layer-circle block-body of multi-body system of digital human body. |
