Mechanical concept development using principle solution models

IOP Conference Series Materials Science and Engineering, vol. 1097, pp. 012001

Abstract

Abstract Cyber-physical systems (CPS) are characterized by the interaction of mechanical, electronic and information technology subsystems. Model-Based Systems Engineering (MBSE) is an approach for the cross-domain development of CPS and requires compatible methods and models for a function-oriented collaboration of the domains. However, the mechanics operate mainly component-oriented and thus cannot participate in the function-oriented development process. We propose a new modeling method that allows mechanics to develop a consistent and function-oriented system model from requirements and functions to principle solutions. The principle solution formally specifies the physical effect, active surfaces and material through which a function is fulfilled. Since principle solutions are consistently parameter-based, they can be calculated by linked external models and checked against requirements. This enables to examine possible solutions for functions at an early stage without having to develop components. Since principle solutions consist of recurring elements, we also propose a modeling concept for a solution libraryso that proven models can be efficiently reused and the modeling effort is reduced. Modeling method, test and solution library are explained using the example of an electric water pump of an automotive cooling circuit.
