【摘要】：大型激光装置是集中了激光、精密仪器,多种光机电控制及计算机控制系统为一体的综合性高科技工程系统,该装置规模庞大,系统结构复杂,元器件数目繁多,结构的复杂性决定了其装校流程的复杂性。装校流程涉及到生产能力和效率评估,即在一定的资源约束和空间约束下,对资源分配,人员调度,方案选择进行决策分析及风险控制。研究装置的流程仿真可以确保计划能按照预定的时间,资源和预算进行。本文首先对整个装置的背景及研究现状进行了概述,接着对激光装置装校作业流程的建模与仿真方法、步骤及意义作了介绍。然后对整个装置的安装流程根据结构组织形式进行层次划分,进行系统建模。选择主放系统的片状放大器组件作为研究对象,将有向图进行扩展,加入资源约束的定义关系,建立装校流程的网络图建模,用图形化的模型表达方式清晰地展现出片放组件相关模块的装校流程。在系统建模的基础上,以Flexsim物流仿真软件为仿真平台,进行仿真建模实例验证,将仿真结果与实际情况进行比较,以此为基础进行整体装校系统设计,以JIT的准时化生产模式为指导思想,在给定的布局方案下,对不同的资源配置进行仿真,并对仿真结果进行比较分析,验证可行性,分析安装效率。最后,针对怎样实现装校作业流程数据的快速修改和提高仿真效率等实际问题,研究数据驱动的仿真方法,建立用户对象实体模型库和装校流程数据库,并在Flesim中进行初步仿真实验。本文的研究成果能够为激光装置的数字化建造提供一定的技术支持。
[Abstract]:The large-scale laser device is a comprehensive high-tech engineering system which integrates laser, precision instrument, various optical-electromechanical control and computer control systems. The device is large in scale, complex in structure, and numerous in the number of components and devices. The complexity of the structure determines the complexity of the process. The process involves the evaluation of production capacity and efficiency, that is, under certain resource constraints and spatial constraints, the decision analysis and risk control of resource allocation, personnel scheduling and scheme selection are carried out. The process simulation of the research facility ensures that the plan is carried out according to scheduled time, resources and budget. In this paper, the background and research status of the whole device are summarized, and then the modeling and simulation methods, steps and significance of the calibration process of laser installation are introduced. Then, the installation process of the whole device is divided into layers according to the structure, and the system is modeled. The chip amplifier module of the main amplifier system is selected as the research object, the directed graph is extended, the definition of resource constraints is added, and the network diagram modeling of the calibration process is established. The graphic model is used to show the process of assembling and calibrating the module. On the basis of system modeling, using Flexsim logistics simulation software as the simulation platform, the simulation modeling example is verified, and the simulation results are compared with the actual situation. Based on JIT's just-in-time production mode, the different resource allocation is simulated under the given layout scheme, and the simulation results are compared and analyzed to verify the feasibility and analyze the installation efficiency. Finally, aiming at the practical problems, such as how to quickly modify the data and improve the efficiency of simulation, the data-driven simulation method is studied, and the user object entity model base and the database of assembly and calibration process are established. A preliminary simulation experiment is carried out in Flesim. The research results in this paper can provide certain technical support for the digital construction of laser device.
