摘要
为了定性定量地评估民航机务维修人员在工作过程中承受的工作负荷,提出基于动作捕捉技术的人机交互工作负荷的评价方法.首先根据动作数据以及人体参数创建数字虚拟人,并根据欧拉四元数运算规则驱动虚拟人在虚拟空间中运动;然后采用逆动力学与Roberson-Wittenburg方法推导虚拟人在执行维修任务过程中所承受的关节力,并用人体的实际用力与人体的最大可用力的比值来衡量维修人员在维修过程中与维修对象交互时产生的工作负荷;再使用动作捕捉设备,针对4个常见的机务维修任务在停机坪上进行维修工作实验,获取相应的动作数据并计算出相应的工作负荷.实验结果表明,文中方法可以快速地计算出实验人员在进行维修作业时的工作负荷,并且其计算结果与人的主观反馈一致.
In order to evaluate the workload borne by civil aviation maintenance personnel in the course of work qualitatively and quantitatively,a method of man-machine interaction workload evaluation based on motion capture technology is proposed.Firstly,a digital virtual human body is created by the motion data parameter,and the virtual human is driven according to Euler’s quaternion rules in virtual space.Then the joint force,the virtual man sustains during maintenance is inferred according to inverse dynamics and the Roberson-Wittenburg method,and the workload is calculated by the ratio of the actual force of the human body to the maximum force of the human body when maintenance personnel interacts with maintenance objects.Next,the motion capture equipment is used to carry out the maintenance work experiment on the tarmac for four common maintenance tasks to obtain the corresponding motion data and calculate the corresponding workload.The experimental results show that the method in this paper can quickly calculate the workload of the experimenters during maintenance work,and the results are consistent with the subjective feedback.
