The Tribomechadynamics Research Challenge: Confronting Blind Predictions for the Linear and Nonlinear Dynamics of a Novel Jointed Structure with Measurement Results
Özgüven, Hasan Nevzat; et. al. (2023-3-8)
The present article summarizes the submissions to the recently announced Tribomechadynamics Research Challenge. The task was a blind prediction of the vibration behavior of a system comprising a thin plate clamped on two s...
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...
The TRChallenge – Experimental quantification of nonlinear modal parameters and confrontation with the predictions
Özgüven, Hasan Nevzat; Bhattu, Arati; Jamia, Nidhal; Hermann, Svenja; Muller, Florian; Scheel, Maren; Schwingshackl, Christoph; Krack, Malte (2023-2-13)
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 ...
Determination of Nonlinear Joint Forces and Nonlinear Identification of Jointed Connections Using FRFs
Soleimani, Hossein; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2023-01-01)

Non-linear Dynamic Modelling and Analysis of Split-Torque Face-Gear Drive Systems
Özgüven, Hasan Nevzat; Aydoğan , Mustafa Özgür; Sarıbay, Zihni B. (2023-1-01)
A non-linear dynamic model of a multi-mesh involute spur pinion-driven face-gear split torque drive system is developed. The lumped mass model consists of five pinions and two face-gears with seven rotational degrees-of-fr...
Experimental Modal Analysis of Geometrically Nonlinear Structures by Using Response-Controlled Stepped-Sine Testing
Karaağaçlı, Taylan; Özgüven, Hasan Nevzat (2022-01-01)
The everlasting competition in the industry to achieve higher performance in aircraft, satellites, and wind turbines encourages lightweight design more than ever, which eventually gives birth to more flexible engineering s...
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...
