VIBRATIONS DUE TO IMPACT IN A NON IDEAL MECHANICAL SYSTEM WITH A NON-LINEAR HERTZIAN CONTACT MODEL
(Amer Soc Mechanical Engineers, 2014-01-01)
This work analyses the post impact behavior of a mechanical system consisting of an oscillator and an unbalanced non ideal electrical motor. The impact between the mechanical system and a rigid wall is based on the assumption ...
Vibrations due to impact in a non ideal mechanical system with a non-linear Hertzian contact model
(2014-01-01)

Bifurcation Analysis of a Piecewise-Smooth Freeplay System
(2022-01-01)
Physical systems that are subject to intermittent contact/impact are often studied using piecewise-smooth models. Freeplay is a common type of piecewise-smooth system and has been studied extensively for gear systems ...
Active control in rotating machinery using magnetic actuators with linear matrix inequalities (LMI) approach
(2009-12-01)
The recent years have seen the appearance of innovative system for acoustic and vibration attenuation, most of them integrating new actuator technologies. In this sense, the study of algorithms for active vibrations control ...
Continuous production of metal matrix composites from the semisolid state
(2013-01-01)
Continuous strip metal matrix composite (MMC) casting of 0.3 mm diameter hard-drawn stainless steel (316L) wire in a quasi-eutectic SnPb (64Sn36Pb) matrix was performed by a two-roll melt drag processing (TRMDping) method, ...
Microstructural Evaluation of an Ultisol and its relation to the history of tension and soil management
(Fundacion General Univ Politecnica Madrid, 2014-01-01)
The lack of information of the microstructure of the soil and its association with physical and mechanical, not always possible to assess the actual effect of stress history, land use. However, the use of micromorphology ...
