| 中文摘要: |
| 力触觉再现关键技术之一是物理模型和碰撞检测算法的构建。以7自由度力触觉设备为基本构架，介绍了力触
觉设备的反馈机理和电气组成；分析比较了力触觉建模的特点，研究弹簧一质点模型，给出了弹簧一质点模型的面模型和
体模型的具体表现形式；分析了力触觉再现碰撞检测算法的优劣，实现了AABB包围盒的遍历算法。最后在Chai 3D环
境构建一个操作手与虚拟柱体的力触觉交互反馈模型，分析了在3种交互情况下的反馈力情况。本文可为力触觉再现
技术的深入研究提供理论参考。 |
| 英文摘要: |
| Physical model and collision detection algorithm are the key to the haptic rendering. The 7 dof haptic device
was taken as example to introduce the feedback mechanism and electrical structure of haptic device. The haptic modeling
method was analyzed and compared. The spring-mass model was introduced, and the plane structure model and solid
model of spring-mass model was given. The advantages and disadvantages of the haptic rendering were analyzed , and the
traversal algorithm of AABB method was proposed. The haptic interaction model of operation tool and virtual cylinder
was set up in Chai 3D. The force feedback situation was analyzed to provide the theoretical basis for the research of
haptic rendering. |
