Differential evolution based identification of automotive hydraulic engine mount model parameters
(2000)
Hydraulic engine mounts are commonly used in an automotive applications, and numerical models exist for performing full-vehicle noise, vibration and harshness (NVH) studies by means of multibody simulation. The parameters ...
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 ...
Thixotropy of semisolid metals
(Materials Research Society, 2000)
Understanding the time-dependent flow behavior of metal alloys in semisolid state is essential for the further development of the process. In the present investigation, the thixotropic behavior of semisolid slurries is ...
Structure-based turbulence modeling for wall-bounded flows
(2000)
The performance of Reynolds stress transport (RST) models in non-equilibrium flows is limited by the lack of information about two dynamically important effects: The role of energy-containing turbulence structure ...
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 ...
Model reduction of modal representations
(American Society of Mechanical Engineers (ASME), 2006)
Dynamic analysis is extensively used to study the behavior of continuous and lumped parameter linear systems. In addition to the physical space, analyses can also be performed in the modal space where useful frequency ...
Transient flow characteristics and properties of semi-solid aluminum alloy A356
(Affiliation: Advance Casting Research Center, Metal Processing Institute, WPI, Worcester, MA 01609, United StatesAffiliation: Department of Mechanical and Industrial Engineering, University of Cyprus, P.O. Box 20537, 1678 Nicosia, CyprusCorrespondence Address: Tonmukayakul, N.Advance Casting Research Center, Metal Processing Institute, WPI, Worcester, MA 01609, United States, 2004)
Development of numerical models to simulate flow characteristics of semi-solid metals in the die cavity requires a good understanding of the transient and equilibrium flow properties of semi-solids and knowledge of the ...
Magnetohydrodynamic turbulence at moderate magnetic Reynolds number
(2004)
We consider the case of homogeneous turbulence in a conducting fluid that is exposed to a uniform external magnetic field at low to moderate magnetic Reynolds numbers (by moderate we mean here values as high as 20). When ...
A grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003
(2008)
Computational complexity theory inspires a grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003. A novel complexity analysis estimates that structured programming time grows at least quadratically with ...
