Experimental Modal Analysis of an Automotive Powertrain [PDF]
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
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.

Reconstruction of damping properties for bended specimen
A general machine or structure is manufactured by combining a plurality of members, and these members may be used as they are in a simple shape or may be used after being shaped. When performing the dynamic design of such machines or structures by Finite
