Microelectronic modular system for sensor-integrating machine elements—model-based configuration and prototypical implementation of sensor-integrating bolts

Abstract In the Priority Program 2305 of the German Research Foundation, so-called Sensor-integrating Machine Elements (SiME) are to be developed. These are essentially highly standardised components with integrated microelectronics. This article presents the development of a model-based construction kit to support the design of integrated sensor systems for these new machine elements. A methodical procedure for collecting the development data required for modelling the construction kit is presented. Use cases, system architecture and module diagrams were developed and modeled for the machine element bolt. These are then linked in SysML models to enable sensor systems to be configured in line with requirements. An exemplary prototype of a sensor-integrating bolt has been developed an validated in a test environment. The modeling of modular system architectures deepens the understanding of the underlying mechatronic system and allows for application-specific configuration of sensor systems by taking differentiation features into account while exploiting synergy potentials between SiME. This configuration represents an approach to making sensor-integrating machine elements accessible to a broad range of users with different requirements.
