Experimental Modal Analysis of an Automotive Powertrain [PDF]
Applied Mechanics and Materials, 2010 The work is devoted to study the dynamic properties of a powertrain, performing an experimental modal analysis (EMA). The aim is to determinate structural modes and frequency response function (FRF) using an experimental approach. Two types of excitation mechanism are applied and compared for the EMA: a modal exciter (electromagnetic shaker system) and

Attenuation of sound radiation in concrete structure through the reduction of mechanical vibration
Revista IBRACON de Estruturas e Materiais, 2018 The efficiency of sound irradiance in structure has direct relation with its vibratory movement. Dynamic vibration absorbers (DVAs) are a low cost viable option for reducing vibrations in passive structures.

The stability of a rising droplet: an inertialess nonmodal growth mechanism [PDF]
, 2015 Prior modal stability analysis (Kojima et al., Phys. Fluids, vol. 27, 1984) predicted that a rising or sedimenting droplet in a viscous fluid is stable in the presence of surface tension no matter how small, in contrast to experimental and numerical ...

Experimental modal analysis of reinforced concrete square slabs [PDF]
, 2015 The aim of this paper is to perform experimental modal analysis (EMA) of reinforced concrete (RC) square slabs. EMA is the process of determining the modal parameters (Natural Frequencies, damping factors, modal vectors) of a structure from a set of ...
