摘要
为研究修井机操作舱内刹把铰接位置与人体疲劳的关系,以XJ30修井机操作舱为例,应用Anybody Modeling System(AMS)软件建立修井机司钻工与刹把的人机交互仿真模型,对司钻工拉刹把动作进行逆向动力学仿真分析。将人体最大肌肉激活度作为疲劳评价指标,分别得到了P_5、P_(50)、P_(95)百分位人体最大肌肉激活度与刹把铰接位置的关系;应用最小二乘法理论建立最大肌肉激活度三次拟合方程,并对拟合方程的误差进行分析。可为修井机操作舱内刹把铰接位置的优化设计,以及拉刹把动作引起的人体疲劳定量评价提供参考依据。
To study the relationship between the human-body fatigue and hinge joint position of brake handle in workover rig＇s control cabin, human-machine interaction models of driller-brake handle about workover rig are established in Anybody Modeling System（AMS）using a type of XJ30 of workover rig as an example, and inverse dynamic simulation is operated in AMS. Based on the 5 th, the 50 th and the 95 th percentiles of max-muscle activity evaluation index of fatigue, the relationships between max-muscle activity and hinge joint position of brake handle are established. Then the cubic fitting equations on the max-muscle activities are built using the least square method. Supports are provided on the optimization of layout of workover rig＇s brake handle and quantitative evaluation of the human-body fatigue caused by pulling workover rig＇s brake handle.
