摘　　要：目的对人体主要关节活动舒适性进行评价。方法参照国军标中的规定,确定出所要评价的关节及关节活动,由20位健康的男被试者参加,根据主观感觉利用自由模量幅度估计法,对其站姿和坐姿时相应关节活动的舒适性进行评价,确定出相对不舒适度指数,以描述关节活动总体舒适度的变化情况。结果主观感觉的不舒适程度受关节、关节活动类型以及活动角度等方面的影响。结果显示,在试验测试的8个关节中,主观感觉最舒适的关节活动在肩部,而最不舒适的关节活动在髋部。结论研究中提出的方法和结果可以为航空设计部门的工效评估以及姿态舒适性方面的军标制订提供参考和指导。Objective To evaluate the discomfort degree of some joint motions. Method Joints and joint motions were selected by referring to the national military standards, Twenty healthy male subjects participated in the experiment, discomforts for varying joint motions in standing and sitting postures were measured using the free modulus magnitude estimation, Relative discomfort index were educed to described overall change of discomfort degree of joint motions, Result Perceived discomfort were affected by the joints, type of joint motions, and angle of motion. Results showed that the most comfort joint motions existed in the joint of shoulder and the most discomfort motion was in the hip in the experiment, Conclusion The method and result in this study can provide reference and guidance for ergonomical evaluation by aviation design department, and drawing up of the military standards about postures comfort.
