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。To address the inefficiency of human model animation,the difficulty of maintenance resources'optimal allocation and the incapability on concurrent optimization of maintenance processes,a knowledge-based virtual aviation maintenance technology was studied.The technology consisted primarily of knowledge-based human model animation,maintenance resource management and maintenance process management.Ontology-based knowledge models were constructed for virtual aviation maintenance.An interaction object was sensed and recognized with 3D model matching;hand interaction postures were pushed to animate virtual hands according to the object.With tool-fastener matching rules and a priority evaluation model for tool allocation,virtual maintenance tools were pushed to assemble or disassemble a selected fastener.Based on semantic similarity,a maintenance process model was retrieved and reused;maintenance steps in the model were indicated and modified during the simulation.The technology was illustrated with applications in the experiment of grasping maintenance tools and some helicopter maintenance simulations.
