Abstract:
This study examined the impact of mechanical oscillation on a hydraulic directional control valve. Particular attention was paid to the oscillating movement of the spool of the hydraulic directional control valve resulting from this impact. Different models of fluid and mixed friction were considered. The models analysed accounted for the relative movement of the directional control valve body and the fact that it is kinematically excited by external mechanical oscillations. It was observed that the mixed friction model, where the frictional force is considered to be the sum of molecular force

Abstract To further optimise the bullet-proof performance of textile reinforced composites, multi-directional friction tests of aramid and ultra-high molecular weight polyethylene (UHMWPE) yarns were carried out by the slope method. The influence of the included angle between the high-performance yarns on the static friction coefficient for aramid and UHMWPE yarns was studied by measuring the friction coefficient. The relationship between the static friction coefficient and the included angle among the high-performance yarns was discussed. The results showed that the friction coefficient of ar

To improve the performance of elastic current-carrying friction pairs, this study employs a wire–plate friction pair and investigates the effect of surface texture orientation on current-carrying friction performance using a self-made micro-sliding current-carrying friction wear tester.

At 0°, the lifespan is the longest, exceeding 500 cycles, followed by 90° with a lifespan of 394 cycles, and the shortest lifespan is observed with multi-directio

Frictional performances of different textures, including axisymmetric and directional patterns, have been tested in the mixed and the hydrodynamic lubrication regimes. Experimental results, corroborated by numerical simulations, show that the leading parameter is the geometrical pattern void ratio since a large number of dimples offers, at low speed, a trap for debris whereas, at high speed, due to the flow expansion in each micro-hole, fosters a fluid pressure drop, the consequent insurgence of micro-cavitation and, ultimately, the reductions of the shear stresses.

Nevertheless, the influence of various earthquakes' properties on the behavior of base-isolation systems subjected to bi-directional seismic loading is still unclear.

AbstractThe relationship and the applicable conditions between Mohr–Coulomb model and linear Drucker-Prager model were discussed, and the results showed that when the friction angle was less than 22° Drucker-Prager model was more suitable for modelling the soil unit; When the friction angle was more than 22°, the Mohr–Coulomb model should be used. In order to further study the compaction characteristics of vibratory roller and the dynamic relationship between vibratory roller and soil, the finite element model of “vibrating roller-soil” was established. The simulation results showed that vertical stress of the soil distributed symmetrically along the axial direction of the vibrating drum, shift forward along the direction of the vibration drum, and decreased sharply with the increasement of the depth. Then experiments carried out showed that acceleration of the vibrating drum was positively correlated with the compaction times, which verified the model was basically correct. Moreover, the regression equation between the compaction degree and the effective value of acceleration was obtained, which provided the idea for the new compaction degree monitoring system.

Although durable, these metallic downhole components can experience failure during oil recovery. These failures usually stem from accumulated fatigue induced by corrosion mechanisms. The dilapidation of these costly crucial components often leads to expensive downtimes, lost production, and unnecessary maintenance costs, which can all be exacerbated by frequent failures.

Improving the accuracy of oil and gas well design is critical to reducing the risk of structural failure over the well's life cycle, particularly for production and injection column components.

Abstract:
The multiple trench friction pendulum system (MTFPS) which has numerous sliding interfaces in each of two perpendicular directions can provide different natural periods, displacement capacities and damping effects at various levels of displacements in the individual direction. In order to characterize the mechanical behavior of the MTFPS isolator under multi-directional earthquakes, a plasticity model named as the multiple yield and bounding surfaces model is proposed in this study. Investigations for buildings isolated with TFPS isolators and subjected to multi-directional excitations have be

Abstract:
The increasing demand for energy efficient vulcanization of rubber extrusions requires the optimization and further development of existing processes. Microwave vulcanization allows the energy required for this process to be coupled directly into the material via dielectric losses. Microwave heating requires the polarity of the rubber so that the electromagnetic wave can cause the polar components of the material to vibrate. These vibrations cause internal friction, resulting in an increase in the temperature of the rubber compound. In this research project, microwaves were used to heat a rubb

Abstract:
Obtaining reliable estimates of aerodynamic roughness is necessary to interpret and accurately predict aeolian sediment transport dynamics. However, inherent uncertainties in field measurements and models of surface aerodynamic properties continue to undermine aeolian research, monitoring, and dust modeling. A new relation between aerodynamic shelter and land surface shadow has been established at the wind tunnel scale, enabling the potential for estimates of wind erosion and dust emission to be obtained across scales from albedo data. Here, we compare estimates of wind friction velocity (u*)

Abstract:
The motivation for this project developed from testing of a full scale building isolated with triple friction pendulum bearings on the E-defense shake table in Japan. The test demonstrated experimentally that the vertical component of ground motion can amplify both the base shear and the story acceleration in the isolated building. Vertical shaking introduced high-frequency variation in the axial force of the bearings, and, consequently, a high-frequency component in the bearing lateral force, which excited higher structural modes in the building. Since vertical bridges are flexible in the ver

Abstract:
Bridges often serve as key links in local and national transportation networks. Bridge closures can result in severe costs, not only in the form of repair or replacement, but also in the form of economic losses related to medium- and long-term interruption of businesses and disruption to surrounding communities. In addition, continuous functionality of bridges is very important after any seismic event for emergency response and recovery purposes. Considering the importance of these structures, the associated structural design philosophy is shifting from collapse prevention to maintaining funct
