Vibration suppression of an elastic beam via sliding mode control
Itik, Mehmet; SALAMCİ, METİN UYMAZ; Ulker, F. Demet (2005-09-09)
This paper presents experimental results of sliding mode control (SMC) technique applied to an elastic beam. The aim of the controller is to suppress first two vibration modes of the beam. Mathematical model of the beam is a finite dimensional model obtained from the Bernoulli-Euler beam equation. As the system states are to be available in order to design the SMC, an observer has been designed to obtain the states of the system by measuring tip deflection of the beam. By using observed states of the finite...
Vibration Analysis of a Cracked Beam on an Elastic Foundation
Batihan, Ali Cagri; Kadıoğlu, Fevzi Suat (2016-06-01)
The transverse vibrations of cracked beams with rectangular cross sections resting on Pasternak and generalized elastic foundations are considered. Both the Euler-Bernoulli (EB) and Timoshenko beam (TB) theories are used. The open edge crack is represented as a rotational spring whose compliance is obtained by the fracture mechanics. By applying the compatibility conditions between the beam segments at the crack location and the boundary conditions, the characteristic equations are derived, from which the n...
Vibration fatigue analysis of structures installed on air platforms
Eldoğan, Yusuf; Ciğeroğlu, Ender; Department of Mechanical Engineering (2012)
Although a component satisfies all operating static requirements, failures can still occur due to vibration induced fatigue. Vibration induced fatigue is a frequent phenomenon, in cases where the natural frequencies of the structures are excited by the loading. Hence, the methods which consider all dynamic characteristic of the structure should be used to obtain accurate fatigue life predictions. These methods in frequency domain are called vibration fatigue methods which give accurate, reliable and fast re...
Vibration fatigue analysis and testing of notched beams
Demirel, Gürzap İsmail; Kayran, Altan; Department of Aerospace Engineering (2019)
Mechanical fatigue is an important phenomenon when the structures are exposed to dynamic, fluctuating loadings. Especially aerospace structures are commonly exposed to random vibration loadings. Even if the components are stable and durable for static requirements, vibration fatigue failures can occur due to the dynamic and fluctuating loadings. Moreover, if the loading frequency has a wide bandwidth as in random vibration loadings, the natural frequencies or resonance regions of the structures are disturbe...
Vibration fatigue analysis of equipments used in aerospace
Aykan, Murat; Kadıoğlu, Fevzi Suat; Department of Mechanical Engineering (2005)
Metal Fatigue of dynamically loaded structures is a very common phenomenon in engineering practice. As the loading is dynamic one cannot neglect the dynamics of the structure. When the loading frequency has a wide bandwidth then there is high probability that the resonance frequencies of the structure will be excited. When this happens then one cannot assume that the structures response to the loading will remain linear in the frequency domain. Thus to overcome such situations frequency domain fatigue analy...
