2. Crecimiento de grano tridimensional con partículas móviles usando método de Monte Carlo
ABSTRACT In this paper we present a simulation model of grain growth with moving particles in three dimensions using the Monte Carlo method. The effect of concentration and particle size on grain size was studied. In general, it was possible to observe the migration of the particles towards the grain boundaries and the braking that they produce on the moveme

3. Adaptive Fuzzy Sliding-Mode Control of Wheel Slide Protection Device for ER24PC Locomotive
Abstract Wheel Slide Protection Devices (WSPD) are employed in railway vehicles to maximize the average of the possible frictional braking force, which is a nonlinear function of the slip ratio of the wheel sets. In this paper, to control the WSPD, a low-order model is presented and un-modeled dynamics are considered as uncertainties. Due to the nonlinear dy

4. The inertial effect of acceleration fields on a self-decoupled wheel force transducer
AbstractWheel force transducer (WFT) is a tool which can measure the three-axis forces and three-axis torques applied to the wheel in vehicle testing applications. However, the transducer is generally mounted on the wheel of a moving vehicle, when abruptly accelerating or braking, the mass/inertia of the transducer itself has extra effects on the sensor resp

5. An optimal integrated longitudinal and lateral dynamic controller development for vehicle path tracking
AbstractIn this paper, an optimal controller for integrated longitudinal and lateral closed loop vehicle/driver dynamics proposed to follow desired path in various driving maneuvers, which also improved maneuverability and stability of vehicle over desired path. Designed controller imposed corrected steering angle and torque on the wheels to keep the vehicle

7. Braking and propulsive impulses in individuals with patellofemoral pain syndrome when walking up and down stairs
"Análise dos impulsos de frenagem e de propulsão em indivíduos com síndrome da dor femoropatelar durante subida e descida de degraus." A síndrome da dor femoropatelar (SDFP) é uma condição clínica prevalente e que afeta o comportamento da marcha. Impulsos de frenagem e propulsão são importantes parâmetros biomecânicos obtidos a partir da força

8. Análise da utilização de pirômetro infravermelho na medida de temperatura no disco de freio durante testes de frenagens / Analysis of the use of pyrometer to measure disc temperature during braking tests
Durante ensaios de materiais de fricção para uso em sistemas de freio automotivo, a temperatura do disco de freio é monitorada por meio de termopares acoplados lateralmente ao disco e logo abaixo da superfície de contato. Na atual pesquisa, realizou-se uma comparação entre a temperatura do disco medido por termopares e sensores infravermelhos durante t

10. Analysis of wear in organic and sintered friction materials used in small wind energy converters
Wind energy converters of small size used in isolated units to generate electrical energy must present low maintenance cost to such facilities economically viable. The aspect to be analyzed in cost reduction is the brake system, since in isolated systems the use of brake is more frequent reducing the brake pads life time. This study aims at analyzing the wea

12. Uma contribuição ao estudo dos freio de atrito para aplicação em frenagem regenerativa / A contribution on the study of friction brakes applied to regenerative braking
A tendência nas grandes metrópoles é de substituir a frota de veículos à combustão por veículos elétricos e híbridos. Estes veículos, em geral, usam banco de baterias como fonte de energia de mobilidade, preservando o meio ambiente, além de armazenar a energia gerada pelo motor durante as frenagens regenerativas, economizando energia. Tais sistema
