摘　　要：考虑到目前通过主观感受评价舒适性的方法不够精确,且针对修井机操纵作业舒适性的研究比较少等问题,以XJ70修井机为例,在生物力学分析软件AMS中建立了典型百分位的中国成年男子人体坐姿数字模型,导入了刹把及座椅模型,对刹把操纵作业进行了逆向动力学仿真;以相关肌群的肌肉活动度为评价指标,研究了座椅高度以及靠背倾角对刹把操纵作业过程中各肌群的影响规律及其映射关系。建立了基于肌肉负荷的操纵舒适性评价模型,为操纵舒适性的量化评价提供了一种新途径,对选择舒适的作业姿势以及座椅可调范围的优化具有一定的指导意义。Considering that the method of evaluating comfort by subjective feeling isn’t precise enough,and there are few studies on the handling comfort of workover rig,taking the XJ70 workover rig as an example,the digital model of the human body sitting posture of Chinese adult males with typical percentiles is established in the AMS biomechanics software,the model of brake handle and seat is imported,and the inverse dynamics simulation of the brake handle operation is performed;Taking the muscle activity of relevant muscle groups as the evaluation index,the influence laws and mapping relationship of seat height and backrest angle on the muscle groups during the brake handle operation are studied.The handling comfort evaluation model based on the muscle loads is built,which provides a new way for the evaluation of comfort and has a certain guiding significance for selecting comfortable operating posture and optimizing the adjustable range of seat.
