Retractable roof structures
j This paper presents a new concept for retractable roof structures. The new structures consist of a foldable lattice of beams connected by cylindrical joints, to which covering panels or membranes are attached. These structures fold towards their perimeter and there is practically no limit to their shape. Solutions to the key problems that have to be solved in the course of the kinematic desig...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولMaking Money by Making Wine: West Coast and Eastern Comparisons
A considerable amount of worthwhile research has been conducted regarding vineyard management and the production of quality wine, but it can be argued that not enough analysis has been done on the economics of wineries. This is unfortunate because the success of the winery business depends on generating ample profits. In an attempt to help in the survival of wineries and to partially fill this ...
متن کاملShape Optimization of Cover Plates for Retractable Roof Structures
Department of Engineering, University of Cambridge Trumpington Street, Cambridge CB2 1PZ, U.K. Abstract The optimal shape of cover plates for circular, symmetric retractable roof structures based on a grid of multi-angulated rods connected by revolute joints is considered. It is assumed that these cover plates are co-planar, and hence they are not allowed to overlap in any configuration; they a...
متن کاملAn Improved Lubrication Model between Piston Rings and Cylinder Liners with Consideration of Liner Dynamic Deformations
The friction pair of piston rings and cylinder liner is one of the most important friction couplings in an internal combustion engine. It influences engine efficiency and service life. Under the excitation of piston slaps, the dynamic deformation of cylinder liner is close to the surface roughness magnitudes, which can affect the friction and lubrication performance between the piston rings and...
