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.
