A framework for three-dimensional finite element analysis of unidirectional and cross-ply composite layups through localized microstructures under hygromechanical conditions
Journal of the Brazilian Society of Mechanical Sciences and Engineering - Tập 42 - Trang 1-12 - 2020
Fiber-reinforced polymers (FRPs) are sensitive to moisture diffusion. Deterioration caused by moisture can limit their service lives considerably. In this work, a three-dimensional finite element modeling and analysis framework is presented to investigate the moisture diffusion kinetics inside fiber-reinforced inside polymer matrix composites by considering different angle and cross-ply orientatio...... hiện toàn bộ

Dynamic nonstationary representations of a railway vehicle considering wheel polygonalization under variable speed conditions
Journal of the Brazilian Society of Mechanical Sciences and Engineering - Tập 45 Số 12 - Trang 1-15 - 2023
Wheel polygonalization is one of the most common failures of the wheelset, which can directly affect the safety and comfort of railway vehicle operation. In the actual condition, traction/braking torque continuously acts on the polygonal wheel fault can result in the modulation of its vibration representation and then influence the effect of the feature exaction of the polygonal wheel faults.

Numerical study of the oil whirl phenomenon in a hydrodynamic journal bearing
Journal of the Brazilian Society of Mechanical Sciences and Engineering - Tập 41 - Trang 1-21 - 2019
The journal bearings are one of the main components of the rotating machines and always bear considerable weight and dynamic stresses. Bearing defect may cause bending and eventually axis fracture and, in some cases, lead to an increase in the temperature of other components. One of the most important challenges of this type of bearings is the instability of the oil film layer, which appears as oi...... hiện toàn bộ
A survey of stability in curved-beam/curved-electrode MEMS element
Journal of the Brazilian Society of Mechanical Sciences and Engineering - Tập 43 - Trang 1-12 - 2021
As the main anti-stability factor, pull-in type of instability has always been a decisive concern in design and usage of micro-electro-mechanical systems. Curved microbeams have been devised to extend the range of stability in these systems. Snap-through is another type of instability which appears as a sudden jump in beam curvature from one configuration to another counterpart state. In order to ...... hiện toàn bộ

An effective structural health monitoring methodology for damage isolation based on multisensor arrangements
Journal of the Brazilian Society of Mechanical Sciences and Engineering - Tập 39 - Trang 1351-1363 - 2016
The development of strategies to evaluate health of mechanical structures has been studied by the international community due to their potential application in the prevention of failures and optimization of maintenance procedures. These systems requires digital signal processing algorithms and interpretation methods, which aim to extract parameters sensitive to the rise of discontinuities in the m...... hiện toàn bộ
Experimental and numerical investigation of flexural behavior of non-uniform thin-walled beams under three-point loading
Journal of the Brazilian Society of Mechanical Sciences and Engineering - Tập 44 - Trang 1-23 - 2022
Side beams are among various types of structures used for reinforcing the safety of automobiles against lateral collisions which have been widely explored. In this study, it was attempted to increment the energy absorption capacity of the beam by creating a non-uniform cross-section with a cosine function at the upper part of the beam. This study was conducted both experimentally and numerically. ...... hiện toàn bộ
Integrated control of braking and steering systems to improve vehicle stability based on optimal wheel slip ratio estimation
Journal of the Brazilian Society of Mechanical Sciences and Engineering - Tập 44 - Trang 1-15 - 2022
This paper presents an integrated control of longitudinal, yaw and lateral vehicle dynamics using active front steering (AFS) and active braking systems. The designed active braking system based on sliding mode controller includes two kinds of working modes. It is activated as an anti-locked brake system (ABS) and an electronic stability control (ESC) with active differential braking strategy (DBS...... hiện toàn bộ
