In recent years, multisegmented mathematical models of the total human body have gained increasing attention in view of the high cost of experiments with human cadavers and/or anthropometric dummies. While these models can simulate very complicated load-motion situations, their effectiveness depends heavily on the proper biomechanical description and modeling of the major articulating joints of the human body. In a research effort to obtain the in vivo biomechanical joint property data suitable for incorporation into these models, the senior author and his associates recently developed a new kinematic and force data collection methodology by means of sonic emitters. By applying and extending this data collection methodology, this paper in Part I presents kinematics for determination of the maximal voluntary hip complex sinus. An overdeterminate number of sonic emitters is utilized and the 'most accurate' three-dimensional kinematic data set is selected by first establishing a selection criterion. Quantitative results obtained from three male subjects are presented in a functional expansion form relative to a locally-defined joint axis system as well as in the form of globographic representation relative to the torso-fixed axis system.
近年来，鉴于人体尸体和/或人体测量假人的实验成本高昂，全身多节段数学模型越来越受到关注。虽然这些模型可以模拟非常复杂的载荷-运动情况，但其有效性在很大程度上取决于对人体主要关节的恰当生物力学描述和建模。为了获得适合纳入这些模型的体内生物力学关节特性数据，资深作者及其同事最近开发了一种借助声波发射器的新运动学和力数据采集方法。通过应用和扩展这种数据采集方法，本文第一部分介绍了用于确定最大自主髋关节复合体窦的运动学。使用了超定数量的声波发射器，并首先建立选择标准来选择“最准确”的三维运动学数据集。从三名男性受试者获得的定量结果以相对于局部定义的关节轴系统的函数展开形式以及相对于躯干固定轴系统的球坐标表示形式呈现。
