It is generally regarded that some properties of the characteristic modes of multiconductor transmission lines, such as per-unit-length impedance, admittance, or characteristic impedance, cannot be meaningfully computed analytically. This inability a

The effect of an elastic coupling on the modal characteristics of a spur gearbox system is investigated using two numerical modal analyses such as rigid coupling and elastic coupling based on the second model of Nelson and Crandall and taking into ac

Helical springs are mostly subjected to compression and expansion in their life cycles under working conditions in vibratory feeder. The continuous reversal stress leads to permanent deformations in pitch of coils of the helical springs due to creep

The main goal of this paper is to propose a simplified model to predict the dynamic behavior; mainly vibration under effects of fluid. Firstly, an experiment is carefully designed incorporating important parameters of the system and experimental moda

Modal Identification from Frequency Response Functions (FRFs) has been extensively investigated up to the point its research reached a stagnation state. Yet, a new approach to determine the modal damping factors from FRFs was recently proposed, showi

To adaptively identify the transient modal parameters for linear weakly damped structures with slow time-varying characteristics under unmeasured stationary random ambient loads, this paper proposes a novel operational modal analysis (OMA) method bas

Vibration-fatigue analysis deals with the material fatigue of flexible structures operating close to natural frequencies. Based on the uniaxial stress response, calculated in the frequency domain, the high-cycle fatigue model using the S-N curve mate

This paper describes a simple and fast numerical procedure to study the steady state responses of assembled structures with nonlinearities along continuous interfaces. The proposed strategy is based on a generalized nonlinear modal superposition appr
