Design and Manufacturing of a New Type Monorail Crane, Moving on Both Hoiızontal and Angular Rails Also Climbing on Vertıcal Rails, by Using Finite Element Analysis

Abstract

This study has been prepared in cooperation University and Industry, 1505, with the support of TUBITAK. The reason why this project is needed, because buildings having curvilinear geometries is required to design a monorail crane moving not only on horizontal rails but also climbing on vertical and curvelinear rails. However, loads can be easily transformed or moved to a high point of a building only by means of curvilinear and vertical rails. At the beginning of design, firstly, the angle between rail and wheel has been optimized considering both isotropic half space assumption and Finite Element Method. After estimated the optimum angle between rail and wheel, the design of wheel has been examined by Finite Element Method. The section area and second moment of inertia of rails used has been optimized or designed in terms of the higher load that the monorail crane is able to remove and transform and stresses occurred on rail has been examined with the assumption of Hertz contact Stresses. Spur gears and worm – gear mechanism, driving the wheels of monorail crane, has been examined considering both AGMA Stress and Strength Equations and Finite Element Method. Lastly the shafts of monorail crane have been examined in terms of both classical mechanics and Finite Element Method.
