RISModeling of Interior Ballistic Gas Solid Flow Using a Coupled Computational Fluid Dynamics Discrete Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In conventional models for twophase reactive flow of interior ballistic, the dynamic collision phenomenon of particles is neglected or empirically simplified. However, the particle collision between particles may play an ...
Series Active Variable Geometry Suspension Robust Control Based on Full-Vehicle Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper demonstrates the ride comfort and road holding performance enhancement of the new road vehicle series active variable geometry suspension (SAVGS) concept using an H∞ control technique. In contrast with the ...
Numerical Study on Effect of Joint Strength Mobilization on Behavior of Rock Masses with Large Nonpersistent Joints under Uniaxial Compression
Publisher: American Society of Civil Engineers
Abstract: In this paper, by analyzing evolution of aperture and contact forces of joints as well as parallel bond breakage, the effect of joint strength mobilization on mechanical behavior of jointed rock masses was studied numerically ...
Multiparameter Sensitivity Analysis of Flexural–Tensile Property of Basalt Fiber–Reinforced Asphalt Mixture
Publisher: ASCE
Abstract: To evaluate the sensitivity of basalt fiber content, length-diameter ratio, and modulus to the flexural–tensile properties of fiber-reinforced asphalt mixture, the spatial random distribution of basalt fibers was realized ...
High-Temperature Mechanical Properties of Artificially Simulated Corroded Q500MC Structural Steel
Publisher: ASCE
Abstract: Steel structures under fire often remain in corrosive environments for a long period of time. However, research on the high-temperature mechanical properties of corroded steels remains limited. In this study, an artificially ...
Safety Impact on Accesses in Two-lane Highways
Publisher: American Society of Civil Engineers
Abstract: On the basis of substantive investigations and data collection which includes the data of highway alignment, traffic volume and accidents, the quantitative impact of the accesses on safety performance of two-lane highways ...
Assemblability, Circuits, Branches, Locking Positions, and Rotatability of Input Links of Mechanisms With Four Closures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general analytical treatment is provided for determining conditions for assemblability, rotatability of input links, locking positions, and number of circuits of mechanisms with four closures ...
Designing a Time Limited–Parking Management Plan for Large-Scale Parking Lots
Publisher: American Society of Civil Engineers
Abstract: The time limited–parking management plan has been widely adopted in curbside parking and in terminal parking. This plan separates parking spaces into several parking groups and manages each group with a specific duration ...
Numerical Study of the Influence of Well Spacing on the Production and Storage of CO2-ECBM
Publisher: American Society of Civil Engineers
Abstract: The spacing between CO2 injection wells and CH4 production wells significantly influences the effectiveness of CO2-enhanced coal bed methane (ECBM) technology. Based on the theory of porous elasticity and seepage mechanics, ...
Effect of Thermal Oxygen Aging on Rheological Properties and Chemical Structure of Lignin-Modified Asphalt
Publisher: American Society of Civil Engineers
Abstract: In recent years, lignin has received increasing attention due to its wide availability, low cost, renewability, and potential for improving the performance of asphalt pavement. The purpose of this study is to investigate ...
