Identification of hysteretic systems using the differential evolution algorithm
(2001)
A widely used model in the field of hysteretic or memory-dependent vibrations is that of Bouc and Wen. Different parameter values extend its use to various areas of mechanical vibrations. As a consequence an identification ...
Efficient treatment of complex geometries for large eddy simulations of turbulent flows
(2004)
Incompressible turbulent flow over a backward facing step at Reh=5100 is investigated by large eddy simulations (LES). The ratio of the oncoming boundary layer thickness δ to the step height h was set to 1.2. Additionally ...
Modelling and control of a medium-duty hybrid electric truck
(2004)
The main contributions of this paper are the development of a forward-looking hybrid vehicle simulation tool, and its application to the design of a power management control algorithm, The hybrid electric vehicle simulation ...
Complexity of distributed parameter bond graph models
(The Society for Modeling and Simulation International, 2014)
Modeling metrics and algorithms that assist the development of dynamic system models are essential for efficient use of modeling and simulation in everyday engineering tasks. Various modeling procedures have been proposed ...
Vehicle model robustness: A case study of the FMTV military truck model
(2005)
Vital to the effectiveness of simulation-based design is having a model of known quality of the system being designed. The purpose of this paper is to validate a simplified dynamic model of an FMTV (Family of Medium Tactical ...
A review of proper modeling techniques
(Affiliation: University of Michigan, Department of Mechanical Engineering, Ann Arbor, MI, United StatesAffiliation: University of Cyprus, Department of Mechanical and Manufacturing Engineering, Nicosia, CyprusAffiliation: Memorial University of Newfoundland, Department of Engineering and Applied Science, St. John's, NL, CanadaCorrespondence Address: Ersal, T.University of Michigan, Department of Mechanical Engineering, Ann Arbor, MI, United Statesemail: tersal@umich.edu, 2008)
A dynamic system model is proper for a particular application if it achieves the accuracy required by the application with minimal complexity. Because model complexity often - but not always - correlates inversely with ...
Determining model accuracy as a function of inputs and system parameters
(American Society of Mechanical Engineers (ASME), 2004)
Vital to the effectiveness of simulation-based design is having a system model of known quality. Previous research introduced an algorithm called AVASIM for assessing model validity systematically and quantitatively. AVASIM ...
A model accuracy and validation algorithm
(American Society of Mechanical Engineers (ASME), 2002)
Dynamic models of physical systems with physically meaningful states and parameters have become increasingly important, for design, control and even procurement decisions. The successful use of models in these contexts ...
Atemplate-based modeling approach for system design: Theory and implementation
(1996)
Previous research has developed search algorithms for deducing Proper Models (minimum complexity models with physically meaningful parameters) of dynamic systems. It has also been proposed that these Proper Models can be ...
