A normalized set of force and permeance data for doubly-salient magnetic geometries
Mahariq, İbrahim; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2009)
In this study, a model is developed to represent doubly-salient magnetic circuits and to fit finite element analysis for the aim of obtaining a set of normalized normal force, tangential force, and permeance variation data. To obtain the desired data FE field solution method is used. The reliability of finite element results have been verified by three steps; first, comparing the numerical results with analytically calculated permeance, second, by solving two switch reluctance motors and comparing the resul...
A methodology for designing tonpilz-type transducers
Çepni, Kerim; Baker, Derek Keıth; Çalışkan, Mehmet; Department of Mechanical Engineering (2011)
Tonpilz-type transducers are the most commonly used projectors in underwater acoustic applications. However, no complete design approach is available in the literature for such transducers. The present study aims to fill this gap in the literature by providing a systematic design approach for the Tonpilz-type transducers. The proposed methodology involves the use of different analytical models and a finite element model of such transducers. Each model provides a different level of accuracy that is tightly c...
Implementation of fractional order viscoelastic models to finite element method
Hesammokri, Parnian; Tönük, Ergin; Department of Mechanical Engineering (2019)
In the latest decades, fractional calculus has been commonly used to define the behavior of viscoelastic materials. Real viscoelastic materials such as rubbers, polymers, soft biological tissues, asphalt mixtures, soils, etc. represent power law creep and relaxation behaviors. In Scientific literature relaxation and creep of this type of material has been modelled, primarily through single and/or linear combinations of exponential functions, in an effort to capture the contributions of both solid and fluid ...
