基于力反馈的虚拟拆卸系统关键技术研究

在虚拟拆装系统的研制过程中,一般要求设计的系统具有尽可能好的“沉浸感”,除了给用户良好的视觉感受外,应尽可能多的增加其它感官感受,例如触觉等。因此,对于力/触觉反馈的研究就变得尤为重要。该文在对PHANTOM Omni 力反馈装置工作原理分析的基础上,运用VC++与OSG 相结合,实现了虚拟物体的拾取和交互式移动,针对典型机械装备,开发了基于力反馈的交互式虚拟拆卸系统。使维修人员对机械产品和维修场景产生最直接的感受与真实的操作体验,提高维修人员的维修质量和效率,降低训练成本。

Research on the Key Technology of Virtual Disassembly System Based onForce Feedback

In the development of virtual assembly system, it is generally required to produceas much as possible the feeling of "immersion". In addition to the user good visual feeling, it isalso required to increase other senses, such as touch, to a most extent. Therefore, it is particularlyimportant to study the force and tactile feedbacks. In this paper, based on feedback analysis deviceworking principle of PHANTOM Omni power, through the use of VC++ combined with OSG, thepickup of virtual objects and interactive mobile is realized. Focusing on the typical mechanicalequipment, the interactive virtual disassembly system is developed based on force feedback,which enables the repair personnel to have the feelings of the most direct and real operationexperience of mechanical products and repair scene, and thus improves the quality and efficiencyof repair personnel and reduces the training costs.
