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 ...
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 ...
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 ...
A simplified structure-based model using standard turbulence scale equations: computation of rotating wall-bounded flows
(2006)
Two linear eddy-viscosity models, the v2-f and k-ω models, have been combined with an algebraic structure-based algorithm for the evaluation of the Reynolds stresses. This closure was originally designed as an integral ...
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 ...
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 ...
