A receptance based method for the calculation of nonlinear normal modes of large ordered structures with distributed localized nonlinearities
Samandari, Hamed; Ciğeroğlu, Ender (2022-12-01)
In recent years, the concept of nonlinear normal modes (NNMs) has gained interest for interpreting a broad range of nonlinear dynamic phenomena. Present study introduces a simple and efficient computational framework to co...
Nonlinear resonances of axially functionally graded beams rotating with varying speed including Coriolis effects
Lotfan, Saeed; Anamagh, Mirmeysam Rafiei; Bediz, Bekir; Ciğeroğlu, Ender (2021-11-01)
The purpose of the current study was to develop an accurate model to investigate the nonlinear resonances in an axially functionally graded beam rotating with time-dependent speed. To this end, two important features inclu...
Nonlinear Vibrations of Rotor-Bearing Systems Supported by Squeeze Film Dampers Due to Unbalance Excitation
Sevencan, Furkan; Ciğeroğlu, Ender; Baran, Özgür Uğraş (2021-11-01)
In this paper, nonlinear dynamic behaviors of a multi-mass flexible rotor-bearing system supported by short length Squeeze Film Damper (SFD) due to the unbalance excitation are presented. The rotordynamic model of the syst...

Development and Verification of Finite Element Model of a Product-Fixture Assembly used for Shaker Testing
Türker, Caner; Özgen, Gökhan Osman; Ciğeroğlu, Ender (2021-02-11)
Vibration reduction of a structure by using nonlinear tuned vibration absorbers
Dogan, Muhammed Emin; Ciğeroğlu, Ender (2021-01-01)
Tuned Vibration Absorbers (TVA) are commonly used in reducing undesirable vibrations of mechanical structures. However, TVAs work in a very limited frequency range and if the excitation frequency is outside of this range, ...
3D linear identification of mechanical joint using FRF decoupling and inverse structural modification methods
Soleimani, Hossein; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2021-01-01)
Copyright © 2021 by ASMEMechanical connections such as bolts and rivets are inevitable in most engineering structures and may significantly affect the dynamic behavior of the structures. Therefore, modeling a joint simply ...
On the solution of nonlinear algebraic equations following periodic forced response analysis of nonlinear structures using different nonlinear solvers
Kizilay, H. Sefa; Ciğeroğlu, Ender (2021-01-01)
In periodic forced response analysis of nonlinear structures, most of the time analytical solutions cannot be obtained due to the complex behavior of the nonlinearity and/or due to the number of nonlinear equations to be s...
