Shock Response of an Antenna Structure Considering Geometric Nonlinearity,r miss under water explosion, pyrotechnic and ballistic shocks. Since most of the antenna structure has larger dimension in longitudinal direction and experience high frequency, high amplitude shock energy, geometric nonlinearity become crucial to predict dynamic behavior in real life. In this study

Investigation on Friction-Excited Vibration of Flexibly Supported Shafting System,ation of the flexibly supported shafting system, such as the acceleration responses of the shaft and the dynamic reaction forces at the propeller support, were measured at different shaft speeds. Experimental results demonstrated that the self-excited vibration, characterized by a single-mode vibrat

Resonant Analysis of Systems Equipped with Nonlinear Displacement-Dependent (NDD) Dampers,orcing is chosen to be close to the natural frequency of the system. The system is modeled and the approximate analytical solution of the governing equation is developed using the multiple scales method (MSM). Several case studies with various amounts of external force’s frequencies are performed to

Performance Comparison Between a Nonlinear Energy Sink and a Linear Tuned Vibration Absorber for Brary system is investigated. An analytic tuning rule for the LTVA when the primary system contains uncertainty is derived. The behavior of the linear system coupled to the NES is analyzed theoretically. A tuning methodology for the NES in the deterministic as well as for the uncertain case is present

Tracking of Backbone Curves of Nonlinear Systems Using Phase-Locked-Loops,ut the systems behavior and the nonlinear normal modes (NNMs) associated with each point of the backbone curve. This information can e.g. be used for system identification. However, the accurate and efficient measurement of the backbone curve in nonlinear systems is still challenging. This contribut

The Importance of Phase-Locking in Nonlinear Modal Interactions,ractions: . interactions, in which there is a specific phase between the interacting modes; and . interactions, in which the modes may interact regardless of their phase. This discussion is accompanied by the study of an example structure in which both classes of interaction may be observed. The str

A Study of the Modal Interaction Amongst Three Nonlinear Normal Modes Using a Backbone Curve Approanderlying linear modes are set to be approximately equal so that .. As a result, the nonlinear normal modes in the system are able to potentially interact with each other. In this study, the underlying unforced and undamped system is considered. The second-order normal forms technique is used to est
