基于目前航空工业部门广泛采用的Delmia软件,从工程应用角度,介绍了实施飞机虚拟维修仿真与评价的一般流程和方法;详细阐述了虚拟维修仿真场景构建、仿真的具体实施、维修性分析与评价方法。结合某型飞机维修性工作的开展,对建立的流程和评价方法进行了广泛的工程应用,实践结果表明,建立的流程和评价方法是适用的、合理的、可行的。 Based on Delmia software which is widely used in aviation industry at present, this paper introduces the general flow and method of implementing virtual maintenance simulation and evaluation of aircraft from the perspective of engineering application. It also expounds in detail the construction of virtual maintenance simulation scenario, the concrete implementation of simulation, maintenance analysis and evaluation method. Combining with the maintenance work of a certain type of aircraft, a wide range of engineering applications have been made to the established processes and evaluation methods. Practice shows that the established processes and evaluation methods are applicable, reasonable and feasible.
