RISLateral Earth Pressure Considering the Displacement of a Rigid Retaining Wall
Publisher: American Society of Civil Engineers
Abstract: In this study, an analytical model is proposed to calculate earth pressure considering the displacement of a rigid wall, and this model is developed based on the hyperbolic soil stress-strain relationship. By introducing ...
A Design Framework for Semi-Active Structural Controlled Adjustable Constant Force Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Semi-active adjustable constant force mechanisms (ACFMs) are an emerging alternative in applications where energy-efficient control of constant force environments is required. However, there is a lack of design strategies ...
An Enhanced Primary Reference Fuel Mechanism Considering Conventional Fuel Chemistry in Engine Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A compact and accurate primary reference fuel (PRF) mechanism which consists of 46 species and 144 reactions was developed and validated to consider the fuel chemistry in combustion simulation based on a homogeneous charged ...
Application of Dynamic د•â€“T Map: Analysis on a Natural Gas/Diesel Fueled RCCI Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, dynamic د•â€“T map analysis was applied to a reactivity controlled compression ignition (RCCI) engine fueled with natural gas (NG) and diesel. The combustion process of the engine was simulated by coupled ...
Mistuned Higher-Order Mode Forced Response of an Embedded Compressor Rotor—Part II: Mistuned Forced Response Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is the second part of a two-part paper that presents a comprehensive study of the higher-order mode (HOM) mistuned forced response of an embedded rotor blisk in a multistage axial research compressor. The resonant ...
Nonlinear Elastic and Inelastic Properties of Cells

Abstract: Mechanical forces play an important role in various physiological processes, such as morphogenesis, cytokinesis, and migration. Thus, in order to illuminate mechanisms underlying these physiological processes, it is crucial ...
The Durability Performance of Polyketone Gears under Various Lubrication Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyketone (PK) is an environmentally friendly engineering plastic with good wear resistance and shows potential in gear applications. In this work, the durability of PK gears under various lubrication conditions was ...
Thermal Management System Modeling and Simulation of a Full-Powered Fuel Cell Vehicle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal management is an important factor in securing the safe and effective operation of a fuel cell vehicle (FCV). A parameterized stack model of a 100 kW proton exchange membrane fuel cell (PEMFC) is constructed by ...
Laser Com-Texture on Ti6Al4V Surface for Lubricant Transportation to Improve Tribological Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Artificial joint materials often wear out due to poor lubrication, affecting their service life. A compound texture (com-texture) was prepared, to improve the spreading of lubricant at the friction interface and reduce the ...
Efficient Model-Free Calibration of a 5-Degree of Freedom Hybrid Robot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pose accuracy is a crucial issue that limits the application of hybrid robots. The model-free calibration instead of complex error modeling is investigated to improve the pose accuracy of a 5-degrees-of-freedom (DOF) ...
