In modern machine architecture, complex mechanical components guarantee the function of the system. Specific maintenance rates reduce maintenance effort and cost. The combination of load and failure monitoring provide data to establish an individual maintenance rate depending on component specific remaining lifetime. In addition, algorithms can optimise the operation strategy to relieve the weakest components and extend the system lifetime. Adapted ball bearings contain a sensor mechanism depending on the relation of beating load and electric bearing impedance to measure load and failure data.
Kurzfassung
Der neue Begriff „Cyber-Physische Zwillinge“ beschreibt die gleichzeitige Entwicklung der Komponenten, Cyber Zwilling (virtuell) und Physischer Zwilling (real), sowie ihrer bi-direktionalen Wechselwirkung. Cyber-Physische Zwillinge unterscheiden sich vom Digitalen Zwilling durch das Angebot von Services zum Beispiel Handlungsempfehlungen im Cyber Zwilling zum Verhalten des Physischen Zwillings. Diese neue Konzeption wird insbesondere mit der Entwicklung und Anwendung sensorintegrierender Maschinenelemente vorgestellt.
This paper discusses the difficulties caused by production precision for a widespread application of sensorial Mechatronic Machine Elements to expand existing machines or designs to Cyber-Physical-Systems. The production induced tolerances lead to an undetermined flow of forces in machine elements and prevent a reliable sensing of forces in Mechatronic Machine Elements. A promising approach to overcome these difficulties is Robust Design, which leads to determined mechanical functions that reduce uncertainty of force measurement in Mechatronic Machine Elements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
