本文介绍了一种测量人体手臂三维动力学特性的方法。端点动力学表征了手部位移与合力之间的关系，在对臂的端点施加三维随机位移扰动的过程中估计。利用频域非参数系统辨识技术确定位移和力之间的输出关系。端点惯性，粘度和刚度参数拟合到所识别的系统。引入了图形技术来帮助可视化这些复杂的动态参数。结果说明了研究三维端点动力学的重要性。
This work describes a method to measure the three-dimensional dynamic characteristics of the human arm. Endpoint dynamics, which characterizes the relationship between hand displacements and resulting forces, was estimated during the application of three-dimensional stochastic displacement perturbations applied to the endpoint of the arm. The dynamic input-output relations between the displacements and the forces were determined using a frequency domain nonparametric system identification technique. Endpoint inertia, viscosity and stiffness parameters were fit to the identified system. A graphical technique was introduced to help visualize these complex dynamic parameters. The results illustrate the importance of studying the endpoint dynamics in three dimensions.
