    Dynamic Modelling and Analysis of Elevator Systems
    (Izmir Institute of Technology, 2016) Berber, Onur; Yardımoğlu, Bülent
    Cities began to grow unexpected size after the industrial revolution. Then, so many new problems like public health, transportation, housing, food requirement etc appeared. Those problems initiated new scientific fields. Engineering diciplines also solved some of those problems and also provided many benefit to people. Different approaches at elevator technology were effected by requirements such as hight travel distances and high load capacities. If the new elevators are compared with the old elevators, it is seen that new ones are more silent, faster, safer and even more efficient. Although the elevator technology goes further and further, its applications become more complex. In this study, in order to find the transient time response of elevator car of the most common elevator types, finite element models of them are developed in ANSYS by using APDL (ANSYS Parametric Design Language). In the analysis, acceleration and deceleration of elevator car are used as input parameters. Time response plots of elevator car are presented.

    Dynamic Analysis of Non-Circular Curved Beam Subjected To Moving Loads
    (Izmir Institute of Technology, 2017) Emre, Melih; Yardımoğlu, Bülent
    In this thesis, analysis of the dynamic responses of non-circular curved beams subjected to moving loads is studied by using ANSYS which is Finite Element software. An APDL (ANSYS Parametric Design Language) code is developed for a parabolic curved beams having fixed-fixed boundary conditions. The moving load is acted on the curved beam as a single load with constant speed during the movement of the load. First of all, the proper number of finite element used in the developed APDL code for curved beam is determined by convergence test. In order to verify the mass and stiffness matrices of the curved beam, natural frequencies are found and compared with the results available in the literature. Then, moving load algorithm used in the developed APDL code is validated by using a straight beam model which has exact solution. After validations, static deflections of curved beam under slowly moving load and dynamic deflections under moving load are presented. Finally, discussion of numerical results are given.

    Modal Analysis of Aerofoil Cross-Sectioned Wing Made of Laninated Composite and Filled With Foam
    (Izmir Institute of Technology, 2015) İskeçe, Barış; Yardımoğlu, Bülent
    Modal analysis of aerofoil cross-sectioned wing made of laminated composite and filled with foam is studied by Finite Element Method with the help of ANSYS which is very powerful and well proven software all around the world. The effects of ratio of overhangs to mid-span and length of the thickened parts on natural frequencies are investigated by finite element models developed in ANSYS and the model is verified by theoretical results available in the literature.
