摘要： 目的 基于计算机辅助三维交互式应用(CATIA)的人机分析模块对肢体康复器械进行上下肢姿态仿真与评估。方法以第95百分位中国男性为标准，在CATIA中对构建的上下肢康复器械引入三维人体模型，建立虚拟人机关系，模拟人在使用上下肢康复器械过程中的姿态并进行评估。结果 人体模型上下肢在均伸展域范围内，且得分≥90分，处于舒适状态；人体各部位的受力均在受力极限之内，各部位的受力力矩均在力矩极限范围内；快速上肢评价中，手臂拉力在各种情况下均为 3~5分，康复器械可以接受。结论 通过对人体模型上下肢伸展域分析、人体姿态评估、快速上肢评价、生物力学分析等，可得出指导性力学数据，为康复器械优化提供科学的依据与方法。

Abstract: Objective To simulate and evaluate the upper and lower limbs posture on rehabilitation devices training with the Computer Aided Tri-Dimensional Interface Application (CATIA) man-machine analysis module. Methods The human body sizes were determined as the 95th percentile Chinese men. Based on the ergonomics analysis of CATIA, three-dimensional human body was constructed in the upper and lower limbs rehabilitation equipment. Virtual human relationship was established. The attitude of the upper and lower limbs in rehabilitation equipment was simulated and evaluated. Results The human limbs model moved in the normal range and the scores were more than 90 which meant comfortable. The forces of various parts of the body was under the stress limit, as well as the force moment. The arm tension was 3-5 points with the rapid upper limb assessment, which meant the rehabilitation equipment was acceptable. Conclusion Rehabilitation robot may be optimized through the model of the human upper extremity stretch domain analysis, body posture assessment, rapid upper limb assessment and biomechanical analysis under CATIA.
