人工关节力学性能测试软件系统的研发
|
摘要
在人工关节生物力学性能研究中,通过离体实验对内植入固定物的生物力学性能进行评价是国际上通用的方法,国内这方面的研究起步较晚,在软件方面的研究更是缺乏。该文在已有的人工关节力学性能硬件测试系统的基础之上,开发了一套基于VC++的软件测试系统,其功能主要包括:硬件控制、数据采集、数据保存、数据处理和显示,可直观展示关节的三维运动轨迹和角度曲线。该软件测试系统能准确、实时地测量出各个关节的运动角度值、外部力矩值、关节间压力值,具有较高的可靠性和稳定性。
In the research of artificial joint biomechanics, it is a common method in the world to evaluate the biomechanical properties of the implanted fixtures through experiments in vitro. The domestic research started late, and the corresponding testing software were lacking. There is still no special software. In this paper, an integrated software test system was designed and built based on the existing hardware system, including: hardware control, data collection, data save, data processing and display. It can directly show the 3D motion trajectory and the angle curve of joints. The system can accurately measure the relative motion angle value, external torque value, and inter pressure value of each joint. It has some reference significance for the development of the artificial joints' evaluation system.
