计算机辅助接触应力测试技术及其在生物力学中的应用

Computer aided contact stress measuring technique and its application to biomechanics

提出两种计算机辅助接触应力测试技术。采用计算机辅助测试技术使接触应力测量具有全场、静动态测试、高度数据自动化等优点。这些特点无疑对接触研究具有重要意义。提出的光学记忆薄膜计算机处理系统及多点导电橡胶计算机辅助测量装置已应用于牙颌接触和关节接触的生物力学研究课题中。这些应用表明计算机辅助测试技术能较好地满足接触力学的实验研究要求。

Two methods of contact stress measurement using computer aided technique are described. The advantages of this technique are full field, both static and dynamic measurements, automatic data processing. These advantages provide the significant values for contacting research. The optical memory wafer with computer processing system and multi point conducting rubber computer aided measuring apparatus presented in this paper have been applied to two research projects of biomechanics. They are occlusion contacting and joint contacting measurements. These application examples show the computer aided testing technique can satisfy the requirements of the contact mechanics research perfectly.
