Use of nonlinear asymmetrical shock absorber to improve comfort on passenger vehicles
(Journal of Sound and Vibration, 2014-03-31) [Artigo]
In this study the behaviour of two different types of shock absorbers, symmetrical (linear) and asymmetrical (nonlinear) is compared for use on passenger vehicles. The analyses use different standard road inputs and include ...
Evaluation of different methods of cooling-lubrication in cylindrical grinding of advanced ceramic dip
(Materials Research, 2014-10-01) [Artigo]
The current work presents a study of alternative methods of cooling-lubrication for the external plunge grinding of advanced ceramics using diamond wheels. These two alternative methods, which are intended to reduce cutting ...
Analisys of thermal efficiency of a modified solar collector type evacuated tube
(Reterm: Engenharia Térmica, 2014) [Artigo]
The need of renewable energy sources due to climate change and thus the search for clean energy sources, justify the growing investment on new types of solar collectors. The research has contributed to this expansion in ...
Application of passive control to energy harvester efficiency using a nonideal portal frame structural support system
(Journal of Intelligent Material Systems and Structures, 2014-03-01) [Artigo]
An analysis of a new energy harvester model is presented, based on a simple portal frame structure, considered a nonideal system due to the kind of excitation influenced by the response of the system, such as a direct ...
Dynamic analysis for different finite element models of beams with viscoelastic damping layer
(Proceedings of the International Conference on Structural Dynamic , EURODYN, 2014-01-01) [Trabalho apresentado em evento]
Many new viscoelastic materials have been developed recently to help improve noise and vibration levels in mechanical structures for applications in automobile and aeronautical industry. The viscoelastic layer treatment ...
Control of slewing motions of flexible structures using shape memory alloy
(ASME International Mechanical Engineering Congress and Exposition, Proceedings (IMECE), 2014-01-01) [Trabalho apresentado em evento]
This paper presents the position and vibration control of a single flexible slewing structure driven by a DC motor at the slewing axis. The position is controlled over the current applied to the DC motor armature. To control ...
