Model-Based Systems Engineering For Efficient Fluid Power

As modern fluid power systems become increasingly complex and diverse, there is a growing need for formal systems engineering processes to aid in the design of such systems. In this paper, we introduce a modelbased systems engineering (MBSE) approach for the design of efficient fluid power systems. In this approach, the systems engineering process is supported with a variety of formal models which allow the experts involved in the process to express and share knowledge precisely, succinctly and unambiguously. In this approach, potential design alternatives are automatically created by searching a compact representation of the design space. Once these alternatives are generated, system-level analysis models are automatically created by synthesizing component-level models captured in model libraries. In order to assess the utility of these architectures, each of these alternatives is optimized using a surrogate modeling approach. The approach is illustrated using the design of a hydraulic backhoe and other simple fluid power design examples.
