Derivation of analysis- and synthesis-methods to manage uncertainty in the development of mechatronic systems with sensor integrating machine elements

将传感器集成到标准化的机器元件中，有望显著加快机械过程中的原位测量。由于机器元件通过其标准化接口促进传感器的集成，因此将这些具有附加传感器功能的机器元件称为传感器集成机器元件（SiME）是合适的。关于机械元件本身的应力水平的知识没有什么意义，但它是更好地理解系统行为和操作条件的关键。机电一体化系统的系统边界包括SiME及其直接设计邻近区域，以及实现电信号和能量传递的设计元素。无论集成传感器如何，机器元件都需要提供其常规功能，它监测系统中的测量量并向传输设备传递信号，再次受到不确定性的影响。信号传输通过电子元件（电缆和连接器）实现，但也通过设计元件（外壳，轴或轴承）的电气特性实现。在系统边界处，一个（扭曲的）信号被传送到连接到系统控制单元的常规信号传输路径。包括SiME及其能量供应和信号传递到过程不同关节的完整传递路径是相关的。该项目的目标是为机电一体化系统的分析和综合提供方法和设计指南，使用SiME实现可靠和可重复的测量量数据采集和信号传输。该项目的重点是管理不确定性，因为机械、热、化学、静电和电磁干扰会影响包括SiME在内的整个传输路径。传递路径包括机械部分，包括SiME和信号传递路径。原位位置消除了干扰，与集成传感器相关的额外干扰需要保持在控制之下。SiME的产品开发本身不是项目的一部分，现有的概念将被利用并放置在系统上下文中。此外，不包括SiME的生产、组件和功能可靠性。因此，有三个问题需要回答：：如何以结构化的方式识别影响SiME全传递路径的相关干扰？在信号传输过程中，哪些干扰会引起信号的改变？如何定性地描述干扰的影响？：可以推导出哪些针对SiME的机电一体化系统的设计准则？SiME设计的第一个通用需求是否可识别？本课题以机械工程中承载系统的不确定性管理方法为基础，对机械与电子结合传递路径的机电一体化系统进行了改进。

The integration of sensors into standardized machine elements is expected to significantly accelerate in-situ measurements in mechanical processes. Since machine elements facilitate the integration of sensors by their standardized interfaces it is suitable to call these machine elements with additional sensorial functions for sensor integrating machine elements (SiME). The knowledge about the stress level of the machine element itself is of no interest but it is the key to better understand system behavior and operational conditions.The system boundary of the mechatronic system includes the SiME and its direct design vicinity as well as design elements enabling electric signal and energy transfer. The machine elements need to deliver their usual functions regardless the integrated sensor, it monitor a measuring quantity in the system and delivers a signal to transferring device being again affected by uncertainty. The signal transfer is realized by means of electronic components (cables and connectors) but also by the electric properties of design elements (housing, shafts or bearings). At the system boundary a (distorted) signal is delivered to a conventional signal transfer path connecting to a system control unit. The full transfer path comprising the SiME as well as its energy supply and signal transfer to the process distinct joint is relevant.Target of this project is to provide methods and design guidelines for analysis and synthesis of mechatronic systems, enabling a reliable and reproducible data acquisition of measuring quantities and signal transfer using SiME.Focal point of the project is the management of uncertainty as a result of mechanical, thermal, chemical, electrostatic and electromagnetic disturbances affecting the full transfer path including an SiME. The transfer path covers the mechanical part including the SiME and the signal transfer path. The in-situ position eliminates disturbances, the additional disturbances associated to the sensor integrated need to be kept under control. The product development of SiME itself is not part of the project, existing concept will be exploited and placed in a system context. Furthermore, production, component and functional reliability of the SiME are excluded.Hence, three question are to be answered:1.: How to identify relevant disturbances influencing the full transfer path of the SiME in a structured way?2.: Which disturbances cause alterations of the signal during its transfer and how can one describe the effect of disturbances qualitatively?3.: Which design guidelines for the synthesis of mechatronic systems with SiME can be derived? Are first generic requirements for the design of SiME identifiable?The project bases on methods for the management of uncertainty of load carrying systems in mechanical engineering, these are enhanced for mechatronic systems with combined mechanical and electronic transfer paths.
