摘要
介绍了基于弹性梁有效变形长度控制的柔顺性触觉再现装置的组成和工作原理。针对大挠度下弹性梁的非线性问题,建立了该装置的有限元模型并进行了数值计算标定。在此基础上又对其进行了静态载荷标定。通过理论值和实际值两方面的对比和分析,验证了该装置的有效性。为研究类似的装置标定问题提供了具有参考价值的思路。
The structure and the principle of compliance haptic display device based on deformable length of elastic element control are introduced. To consider the influence of non-linear factors, the finite element model of the device is built up and numerical calculation calibration based on finite element method of the device are conducted . Then static load calibration of the device is described. According to the comparison and analysis between the theory value and actual one, the compliance haptic display device is proved to be feasible and useful. It may be used as a reference for calibration.
