摘要
针对飞机自动化装配制孔系统下位机开发过程中存在的下位机逻辑复杂、开发难度高的问题,提出了一种支持效率优化的可配置制孔装备控制软件开发方法,可根据工艺信息自动生成飞机自动化装配制孔系统下位机控制软件。对飞机自动化装配制孔流程进行了Petri网建模研究,利用赋时变迁Petri网分析了制孔流程的效率,为配置制孔装备控制软件提供依据。通过定义不同的工艺信息,可配置出适用于不同多轴制孔系统的下位机软件。
Aiming at the problems of complex logic and difficult development in the development of control software of aircraft automatic assembly drilling system,a development method of configurable drilling equipment control software supporting efficiency optimization was proposed.The control software of aircraft automatic assembly drilling system could be automatically generated according to the process information.The Petri net modeling of aircraft skin automatic assembly drilling process was studied.The efficiency of drilling process was analyzed by using Timed Transition Petri Net,which provided the basis for configuring control software.By defining process information,the control software suitable for different multi-axis drilling systems can be configured.The example of the track drilling system shows that the automatically generated control software meets the process requirements in the actual drilling process.The drilling efficiency of the two methods is 5.5/min and 6.1/min respectively,and the consistency of the countersink can reach 0.03mm.
