Vehicle Concept Model Abstractions For Integrated Geometric, Inertial ,Rigid Body, Powertrain and FE Analysis
Abstract
Vehicle analysis models of any kind have their basis in some type of physical representation of the design domain. Rather than describing three-dimensional continua of a collection of components as is done in detail-level CAD models, an architecture-level abstraction describes fundamental function and arrangement, while capturing just enough physical detail to be used as the basis for a meaningful design space representation and eventually, analyses that permit architecture assessment. The design information captured by the abstractions is available at the very earliest stages of the vehicle development process, so the model itself can function as a design space for ideas. In this paper we describe vehicle architecture abstractions appropriate for integrated model extractions suitable for geometric, inertial, rigid body, acceleration, braking, fuel efficiency, structural, and NVH assessments. Additionally, we discuss the requisite level of information required for each analysis type.
