An Algorithm for the Selection of Physical System Model Order Based on Desired State Accuracy and Computational Efficiency
(American Society of Mechanical Engineers (ASME), 2003)
In recent years, algorithms have been developed to help automate the production of dynamic system models, The focus of this development has been to create procedures and algorithms that use modeling metrics for generating ...
A modular modeling approach for the design of reconfigurable machine tools
(Affiliation: Department of Mechanical Engineering, University of Michigan, Ann Arbor, United StatesAffiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, CyprusCorrespondence Address: Ersal, T.Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI, United Statesemail: tersal@umich.edu, 2004)
A new generation of machine tools called Reconfigurable Machine Tools (RMTs) is emerging as a means for industry to be more competitive in a market that experiences frequent changes in demand. New methodologies and tools ...
Ideal physical element representation from reduced bond graphs
(2002)
Previous research has demonstrated that bond graphs are a natural and convenient representation to implement energy-based metrics that evaluate the relative 'value' of energy elements in a dynamic system model. Bond graphs ...
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 ...
Target cascading in vehicle redesign: A class VI truck study
(2002)
The analytical target cascading process is applied to the redesign of a U.S. class VI truck. Necessary simulation and analysis models for predicting vehicle dynamics, powertrain, and suspension behaviour are developed. ...
Energy-based model reduction methodology for automated modeling
(2010)
In recent years, algorithms have been developed to help automate the production of dynamic system models. Part of this effort has been the development of algorithms that use modeling metrics for generating minimum complexity ...
Systematic assessment of rigid internal combustion engine dynamic coupling
(2008)
Accurate estimation of engine vibrations is essential in the design of new engines, engine mounts, and the vehicle frames to which they are attached. Mount force prediction has traditionally been simplified by assuming ...
Extension and application of an algorithm for systematic identification of weak coupling and partitions in dynamic system models
(2009)
This paper reviews and extends a technique to detect weak coupling (one-way coupling or complete decoupling) among elements of a dynamic system model, and to partition and reduce models in which weak coupling is found. The ...
Systematic model decoupling through assessment of power-conserving constraints - An engine dynamics case study
(American Society of Mechanical Engineers (ASME), 2004)
Simplified models for predicting engine mount forces have traditionally been developed based on the assumption that for a well-balanced low-speed engine, the reciprocating dynamics can be decoupled from the three-dimensional ...
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 ...
