采用同步测力、测加速度和多机多分辨率摄像的技术,并对解析原始数据运用“积分平滑”等一系列手段,用以提高逆向动力学计算关节内力的精确性,并且与目前常规逆向动力学方法的计算结果相比较,探讨用这两种不同方法所得结果的可靠性。研究表明,当研究一侧肢体远侧环节受到较大外力作用时,只要测出外力与其压心位置,采用常规逆向动力学方法计算关节内力尚具有一定的可靠性;所采用的一些技术措施,能有效地提高计算的精确性和适应性。
A series of techniques such as synchronous force measurement, acceleration measurement and multi-camera and multi-resolution imaging are adopted, and a series of means such as “integral smoothing ” are used to analyze the original data to improve the accuracy of inverse kinematics in calculating the joint internal force, Conventional inverse kinetics method is compared with the calculated results to explore the reliability of the results obtained by these two different methods. Studies have shown that when the study of the distal part of the limb by a larger external force, as long as the measured force and its pressure center position, the use of conventional reverse kinematics to calculate the joint force still has some reliability; some of the technical measures used, Can effectively improve the accuracy and adaptability of the calculation.
