The Evolution of Power Unit Development Process through MBD

- Standardization of 1D-Model and Application in Power Unit Development -

Abstract

To achieve the high efficiency of power unit development through the application of MBD, 1D system model that can flexibly respond to the refinement of model granularity and domain extension is necessary. The refinement of model granularity requires 1D sub-system models, and domain extension requires models with expanded behavioral representations. This paper presents an initiative for standardizing the 1D system model and discusses the evolution of the development process by applying a virtual development environment that integrates the 1D sub-system models and the expanded behavioral models to power unit development.
