RISNumerical Calculation of Fluid Film Force on Journal Bearings Based on a Biconjugate Gradient-Stabilized Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this work is to present a technical numerical method to improve the efficiency of solving the Reynolds equation for hydrodynamic bearings. Hydrodynamic bearings are largely employed in the shafting of high-speed ...

Signal Optimization at Urban Highway Rail Grade Crossings Using an Online Adaptive Priority Strategy
Publisher: American Society of Civil Engineers
Abstract: In urban areas, conventional transit priority systems (e.g., passive priority) present some problems, such as causing too many traffic delays and degradation of on line performance due to the lack of real-time data. The ...
Modeling Geogrid Pullout Behavior in Sand Using Discrete-Element Method and Effect of Tensile Stiffness
Publisher: American Society of Civil Engineers
Abstract: In this study, a series of numerical pullout tests was performed using the discrete-element method (DEM) to investigate the micromechanical behavior of geogrid pullout and the effect of geogrid tensile stiffness. Geogrid–soil ...
