【摘要】：为解决人体模型驱动效率低、难以优化配置维修资源、不能同步优化维修流程等问题,研究基于知识的航空虚拟维修技术。该技术主要由基于知识的人体模型驱动、维修资源管理和维修流程管理技术组成。首先,基于本体建模航空虚拟维修知识。随后,通过三维模型匹配、感知和识别交互对象;根据对象推送和重用手部交互位姿,以驱动虚拟手。基于工具-紧固件匹配规则、工具配置优先度评价模型,推送能拆装指定紧固件的虚拟维修工具。通过语义相似,检索和重用维修流程模型;在仿真中,提示并修订模型中的各个维修步骤。最后,通过驱动虚拟手抓握维修工具实验和直升机维修仿真案例、验证了该技术的有效性。
[Abstract]:In order to solve the problems such as low efficiency of human model driving, difficult to optimize the allocation of maintenance resources, unable to synchronously optimize the maintenance process and so on. This paper studies the aviation virtual maintenance technology based on knowledge, which is mainly composed of knowledge-based human model driven, maintenance resource management and maintenance process management technology. Modeling aviation virtual maintenance knowledge based on ontology. Then, the interactive objects are perceived and identified by 3D model matching. According to object push and reuse hand interaction posture to drive virtual hand. Based on tool-fastener matching rules, tool configuration priority evaluation model. Push the virtual maintenance tool which can disassemble and assemble the specified fasteners. Through semantic similarity, retrieve and reuse the maintenance process model; In the simulation, the various maintenance steps in the model are suggested and revised. Finally, the effectiveness of this technique is verified by driving virtual handgrip maintenance tools and helicopter maintenance simulation cases.
