In this paper, a manipulability analysis of a new parallel-type rolling mill, named ‘‘paramill,’’ in its conceptual design stage is investigated. The paramill considered uses two Stewart platforms (SPs) in opposite directions for the generation of 6 degree-offreedom motions of individual work-rolls. The objective of this new approach is to pursue an integrated control of the strip thickness, st...

In this paper, the manipulability analysis of a new parallel-type rolling mill “Paramill” in its conceptual design stage is investigated. Paramill uses two Stewart platforms (SPs) in opposite direction for the generation of 6 degree-of-freedom motions of each work-roll. The objective of this new technology is to permit an integrated control of the strip thickness, strip shape, pair-crossing ang...

the purpose of this study is to improve the aerodynamic performance of wind turbine blades, using the ball-spine inverse design method. the inverse design goal is to calculate a geometry corresponds to a given pressure distribution on its boundaries. by calculating the difference between the current and target pressure distributions, geometric boundaries are modified so that the pressure differ...

in this work, an inverse finite element formulation was modified for considering material anisotropy in obtaining blank shape and forming severity of deep drawn orthotropic parts. in this procedure, geometry of final part and thickness of initial blank sheet were known. after applying ideal forming formulations between material points of initial blank and final shape, an equation system was obt...

This study presents an optimization problem for shape design of a 2-D radiant enclosure with transparent medium and gray-diffuse surfaces. The aim of the design problem is to find the optimum geometry of a radiant enclosure from the knowledge of temperature and heat flux over some parts of boundary surface, namely the design surface. The solution of radiative heat transfer is based on the net r...
