RISVertex-Splitting on a Diamond Origami Pattern
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: A diamond origami pattern is a well-known origami pattern consisting of identical six-crease vertices. As each vertex can be modeled as a spherical 6R linkage with three degrees of freedom (DOF), the tessellated pattern ...
Design of Porous Asphalt Mixtures by Using the CAVF Method
Publisher: American Society of Civil Engineers
Abstract: To harmonize the conflict between the durability and drainability of porous asphalt mixtures, the coarse aggregate void filling (CAVF) method is introduced to the design of a porous asphalt mixture. Bulk volume relative ...
A Legendre Polynomials Based Method for Stability Analysis of Milling Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a timedomain approach for a semianalytical prediction of stability in milling using the Legendre polynomials. The governing equation of motion of milling processes is expressed as a delaydifferential ...
Modification of Full Asphalt Content AC Designing Method
Publisher: American Society of Civil Engineers
Abstract: Some key problems of Full Asphalt Content AC (FAC) designing method and improvement measures were undertaken. First, reasons of difference between actual
Hybrid Digital Image Correlation–Finite Element Modeling Approach for Modeling of Orthogonal Cutting Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cutting process modeling is still a significant challenge due to the severe plastic deformation of the workpiece and intense friction between the workpiece and tool. Nowadays, a novel experimental approach based on digital ...
Effects of Process Parameters on White Layer Formation and Morphology in Hard Turning of AISI52100 Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hard turning is becoming increasingly considered by industry as a potential substitute for grinding. However, it is greatly hurdled by surface integrity problems such as tensile residual stress and white layer, which are ...
Harmonic Differential Quadrature Method for Surface Location Error Prediction and Machining Parameter Optimization in Milling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a semianalytical numerical method for surface location error (SLE) prediction in milling processes, governed by a timeperiodic delaydifferential equation (DDE) in statespace form. The time period is ...
Effects of Additives on the Properties of Asphalt Cement
Publisher: American Society of Civil Engineers
Abstract: Asphalt cement is an important part of the asphalt mixture, which is mixed by bitumen, mineral filler and additive, but there are few researches on how can additives improve the properties of asphalt cement effectively. ...
A Comparative Study of Methane Combustion Characteristics With Different Additions in an Optical Spark Ignition Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Natural gas is a promising fuel for internal combustion (IC) engines with minimal modification, whereas its low power output and slow flame propagation speed remain a challenge for automobile manufacturers. To find a method ...
Dynamic Analysis of a High Speed Rotor Ball Bearing System Under Elastohydrodynamic Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear dynamic behaviors of a highspeed rotorball bearing system under elastohydrodynamic lubrication (EHL) are investigated. First, the numerical curve fittings for stiffness and damping coefficients of lubricated ...
