Development of Experimental and Finite Element Models to Show Size Effects in the Forming of Thin Sheet Metals

Morris, Jeffrey D 05 August 2019 (has links)
Abstract An experimental method was developed that demonstrated the size effects in forming thin sheet metals, and a finite element model was developed to predict the effects demonstrated by the experiment. A universal testing machine (UTM) was used to form aluminum and copper of varying thicknesses (less than 1mm) into a hemispherical dome. A stereolithography additive manufacturing technology was used to fabricate the punch and die from a UV curing resin. There was agreement between the experimental and numerical models. The results showed that geometric size effects were significant for both materials, and these effects increased as the thickness of the sheets decreased. The demonstration presents an inexpensive method of testing small-scale size effects in forming processes, which can be altered easily to produce different shapes and clearances.

Materiály pro vinutí elektrických strojů / Materials for electric machine winding

Minks, Ondřej January 2016 (has links)
This work deals with the option of substitute aluminum for copper as winding material in induction motor in several variants and compare them. The advantages and disadvantages of these materials for the application are mentioned. The default element is the machine with power 29 kW, 2p = 4, which is the basis for other variants. It is about the verification of the default copper wire machine with cataloging data and then verification of several aluminum wire variants of the machine. Veryfying the machine designs is performed on the basis of three programs - RMxprt, ANSYS Maxwell and Matlab. In all of these programs, the machine calculations were realized for copper and aluminum winding in point close to the nominal. Final results are evaluated. There are also heat and ventilation calculations of the machine.
