【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。
[Abstract]:Objective to evaluate the comfort of the main joints. Methods according to the provisions of the national military standard, the joint and joint activity to be evaluated was determined, and 20 healthy male subjects were involved. The method of estimating the amplitude of free modulus was used according to subjective feeling. The relative uncomfortableness index was determined to describe the change of the overall comfort degree of joint activity by evaluating the comfort of the corresponding joint activities in the standing posture and sitting position. Results the uncomfortable degree of subjective sensation was influenced by the joint, the type of joint movement and the angle of movement. The results showed that, of the 8 joints tested, the most comfortable joints were in the shoulder and the most uncomfortable in the hip. Conclusion the methods and results presented in the study can provide reference and guidance for the ergonomic evaluation of aviation design departments and the formulation of military standards for posture comfort.
