Mounting system with virtual representation

安装系统及其虚拟表示应整合波鸿鲁尔大学生产系统教席的四个研究小组的研究课题。跨集团的研究课题包括：具有人-机器人-协作工作站的混合装配系统的规划工具，在一个工艺中处理不同和变化的部件变体，生产线平衡，用于变体控制的数字工人辅助和引导系统，以及连接的装配站和工艺的集成网络。这些主题只能在安装系统的真实和完整的组装过程中进一步开发和验证。安装系统的虚拟表示做出了越来越重要的贡献。它们构成了模拟装配过程、进行虚拟调试、离线编程、为数字工人辅助和引导系统提供信息和数据以及实时监控数字孪生兄弟上的过程行为的基础。因此，总体而言，这将有助于优化实际的组装工艺。一个特别的挑战是将混合装配系统中发现的异类组件结构集成到功能虚拟表示中。此外，还应强调人体模拟。由于机器人单元的模拟或纯手工装配工作已经代表了最先进的技术水平，在一个生产过程中人与机器之间的影响的情况下，模拟系统仍然显示出相当大的缺陷。这也适用于人类工作的实时数据采集，以监控数字双胞胎的系统行为。在这里，必须找到技术解决方案，以便记录相关数据，并在正在进行的过程中向数字孪生兄弟提供这些数据。此外，装配中的工艺模拟需要扩展到包括搬运和进给系统。由于可以在振动给料机中发现，利用混沌组分供应来模拟物理组分行为，对于迄今的喂料系统和分离技术的规划几乎没有什么用处。随着LP在动态和不断变化的工艺条件领域的相关基础研究，基于所要求的装配系统的生产系统仿真应该达到比今天的仿真模型更现实和更复杂的水平。LP已经在生产工程和管理、生产数字化、自动化技术以及工业机器人等各个领域和项目中拥有出色的能力。应用的装配系统及其虚拟表示应加强、完善和扩大工业生产中的装配领域，将其作为一个重要的技术装备模块。

The mounting system with its virtual representation shall integrate the research topics of the four research groups of the Chair of Production Systems (LPS) at Ruhr University Bochum. The cross-group research topics are among other things: planning tools for hybrid assembly systems with Human-Robot-Collaboration workstations, handling of different and changing component variants in one process, line balancing, digital worker assisting and guiding systems for variant control as well as with the integrated networking of linked assembly stations and processes. These topics can only be further developed and validated within a realistic and complete assembly process in a mounting system.An increasingly important contribution is made by virtual representations of mounting systems. They form the basis for simulating assembly processes, conducting virtual commissioning, offline programming, providing information and data for digital worker assisting and guiding systems as well as monitoring process behaviour on the digital twin in real time. Hence, this in total shall contribute to optimize the real assembly process. One particular challenge is the integration of a heterogeneous component structure, as found in hybrid assembly systems, into a functional virtual representation. In addition, the human simulation should be emphasized. As simulations of robot cells or purely manual assembly work already represent the state of the art, simulation systems still show considerable deficits in the case of influences between man and machine within one production process. This also applies to the real-time data acquisition of human work to monitor the system behaviour by the digital twin. Here, technical solutions have to be found in order to record relevant data and make it available to the digital twin in the ongoing process. In addition, process simulations in assembly need to be extended to include handling and feeding systems. Simulation of physical component behaviour with chaotic component provision, as they can be found with vibratory feeders, has little use in the planning of feeding systems and separating technology to date. With the associated fundamental research at the LPS in the field of dynamic and changing process conditions, the simulation of production systems on the basis of the requested assembly system should reach a much more realistic and complex level than it is the case in today's simulation models.The LPS already has excellent competences from various fields and projects concerning production engineering and management, digitalisation in production, automation technology as well as industrial robotics. The applied mounting system with its virtual representation should strengthen, complete and expand the field of assembly in industrial production at the LPS as an essential technical equipment module.
