A Novel Approach for Local Structural Modification of Nonlinear Structures
Ceren Ekinci, E.; Bülent Özer, M.; Özgüven, Hasan Nevzat (2024-01-01)
Structural modification methods provide powerful tools to calculate the dynamic behavior of a modified structure from that of the original one. In general, either the modal properties or responses of the original structure...
The TRChallenge: Experimental Quantification of Nonlinear Modal Parameters and Confrontation with the Predictions
Bhattu, Arati; Jamia, Nidhal; Hermann, Svenja; Müller, Florian; Scheel, Maren; Özgüven, Hasan Nevzat; Schwingshackl, Christoph; Krack, Malte (2024-01-01)
In recent years, the prediction of the behavior of structures with high-level nonlinearities has been a challenging area of research. In 2021, the Tribomechadynamics Research Challenge was proposed to evaluate the current ...
Nonlinear Vibration Analysis of a Two-Blade System with Shroud-To-Shroud Contact by using Response Dependent Nonlinear Normal Modes
Ahi, Tahsin; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2024-1)
Periodic forced response analysis of nonlinear real systems is a computationally demanding task. In order to reduce the computational burden, different approaches are proposed in the literature. The reduced computational e...

Bypassing the Repeatability Issue in Nonlinear Experimental Modal Analysis of Jointed Structures by using the RCT-HFS Framework
Özgüven, Hasan Nevzat; Gürbüz, M. Fatih; Karaağaçlı, Taylan (2023-2-13)
Mechanical joints, which are indispensable for almost all mechanical systems, are often an important source of nonlinearity due to frictional, backlash and/or preload effects. Recent studies have shown that the contact pr...
Determination of Nonlinear Joint Forces and Nonlinear Identification of Jointed Connections Using FRFs
Soleimani, Hossein; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2023-01-01)
The Author(s), under exclusive license to Springer Nature Switzerland AG.Identification and modeling of joint dynamics is an important issue in the dynamic modeling of structures with joints. Moreover, structures connected...
Experimental Quantification and Validation of Modal Properties of Geometrically Nonlinear Structures by Using Response-Controlled Stepped-Sine Testing
Karaagacli, T.; Özgüven, Hasan Nevzat (2021-10-01)
Background Various nonlinear system identification methods applicable to distributed nonlinearities have been developed over the last decade. However, many of them are not eligible to accurately quantify a high degree of n...
Ideal tooth profile modifications for improving nonlinear dynamic response of planetary gear trains
Ozturk, Veysel Yalin; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2021-05-01)
The ultimate goal in this study is to investigate the effects of tooth profile modifications (TPMs) on PGTs by performing parametric studies. For this purpose, firstly a nonlinear planetary gear dynamics model with time-va...
3D linear identification of mechanical joint using FRF decoupling and inverse structural modification methods
Soleimani, Hossein; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2021-01-01)
Mechanical 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 and accurately is essent...
