关于人机合作系统的研究已经有很多.在这些研究中，通常最好考虑机器操作过程中人的可操作性和运动，以及考虑机械参数。然而，目前的许多研究仅评估力学参数。虽然一些研究已经评估了人体参数，但这些仍然是主观的。因此，在本研究中，上肢运动和肌肉和大脑的激活过程中的机器操作与惯性和摩擦进行了定量测量。实验条件分为九个等级。然后将这些组合成以下摩擦和质量条件：机器操作期间的摩擦力为3.3 ± 1.2、8.6 ± 2.7或11.5 ± 3.8 N;机器质量为2.2 ± 0.1、3.2 ± 0.2或4.4 ± 0.2 kg。实验结果表明，摩擦力和质量对上肢肌肉激活的影响有显著性差异（p <0.05）。虽然脑分析结果显示摩擦力无显著差异，但质量有显著差异（p <0.05）。实验结果表明，手的位置，上肢肌肉激活和大脑激活的轨迹往往受到质量的影响。
There have been numerous studies on human- machine cooperative systems. In such studies, it is generally preferable to consider human maneuverability and motion during machine operation as well as considering mechanical parameters. However, many of the current studies only evaluate the mechanical parameters. Although some studies have evaluated human parameters, these remain subjective. Therefore, in this study, upper extremity movement and muscle and brain activation during machine operation with inertia and friction were measured quantitatively. The experimental conditions were divided into nine classes. These were then combined into the following frictional and mass conditions: the friction during machine operation was 3.3 ± 1.2, 8.6 ± 2.7, or 11.5 ± 3.8 N; the mass of the machine was 2.2 ± 0.1, 3.2 ± 0.2, or 4.4 ± 0.2 kg. The experimental results revealed significant differences in upper extremity muscle activation with both friction and mass (p <; 0.05). Although the brain analysis results showed no significant difference with friction, significant differences were found with mass (p <; 0.05). The experimental results showed that the trajectory of the hand position, upper extremity muscle activation, and brain activation tended to be affected by mass.
