摘要
针对舱室布局设计评估决策问题,考虑关节力矩对关节舒适性的影响,提出了以上肢操作舒适性评估布局方案优劣的方法。应用CATIA软件进行了主要操作姿势仿真实验,然后根据人体生物力学模型分析关节力矩,通过Kane动力学方程建立了上肢动力学模型,进而借助NASA力量模型将关节力矩引入到关节舒适性评估中,解决了不同关节角度组合时上肢的整体舒适性评估问题。关节角度和上肢操作舒适性关系曲线可为舱室的布局工效评估与优化提供参考,在设计初期阶段考虑人的因素,及时发现设计缺陷,提高设计效率。
In view of the decision problem of cabin layout design,considering the influence of the joint torque on joint comfort,the method to evaluate the layout scheme through the upper limb operating comfort was proposed. The CATIA software was used to simulate the main operating posture,the human body biomechanical model was adopted to analyze joint torque,the upper limb dynamic model was established based on Kane dynamic equation,and the joint torque was introduced to evaluate joint comfort with the help of NASA＇s power model,the evaluation problem of the overall comfort of upper limb with different joint angle combination was solved. The curve of joint angle and the upper limb operating comfort can provide a reference for cabin layout evaluation and optimization. The proposed method can find design flaws in time by considering human factors in the early design stage,and thus improve the design efficiency.
