武器设备虚拟维修拆卸系统设计仿真研究

摘要
虚拟维修作为新兴的维修技术手段,在维修拆卸规划方面存在不足,传统的虚拟维修拆卸系统不重视人体工效因素,规划结果的可行性不高,针对复杂武器装备,其可行的拆卸序列随零部件规模扩大呈指数级增长,普通的图论方法易出现混乱、死锁等现象。在Petri网的基础上引入解释结构模型,对装备零部件进行系统划分和层级划分,简化对维修拆卸过程的描述,将人体工效因素纳入拆卸过程的约束条件,利用jack平台对人体工效指标进行定义、计算和二次开发,并结合遗传算法,定义了虚拟维修拆卸过程的规划目标、约束条件、编解码方式,针对某型变速箱进行了实例分析,验证了系统良好的应用效果。
Virtual maintenance as a means of new maintenance technology,has deficiencies in disassembly planning. For complex weapons and equipment,the quantity of the disassembly sequence increases with the expansion of the scale of components exponentially,and the general methods of Graph Theory are prone to chaos,deadlock and so on. The traditional virtual maintenance disassembly system does not attach importance to ergonomic factors,which causes the planning results unfeasible. On the basis of Petri net,an interpretative structural model is introduced to divide the equipment components and simplify the description of the maintenance disassembly process. The ergonomic factors were included in the disassembly process,and realized by jack platform. Using genetic algorithm to define the planning objectives,constraints,codecs in the process of virtual maintenance disassembly. Taking a certain type of gearbox as the case analysis,the high-efficiency of the system was verified.
