RISDynamic Modeling and Locomotion Control for Quadruped Robots Based on Center of Inertia on SE(3)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Quadruped robots have good mobility and agility in complex environments, but dynamic control of locomotion for quadruped robots has long been a big challenge for researchers. In this paper, we build the center of inertia ...
New Calculation Method and Application of Gas Loss From Coring Shale Gas Well
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas content is one of the most important parameters of shale reservoir evaluation and productivity evaluation. In order to obtain gas content accurately, based on the first law of Fick and material balance equation, ...
Analysis of Convergence Behavior for the Overset Mesh Based Numerical Wave Tank in openfoam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a solution verification and validation study for an overset mesh based numerical wave tank in openfoam, which considers the coupling between a free-surface hydrodynamic flow model, a rigid body motion ...
Analysis of Heat Transfer and Entropy Generation in a Channel Partially Filled With N-Layer Porous Media
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Convective heat transfer in a channel partially filled with porous medium has received a lot of attention due to its wide engineering applications. However, most researches focused on a channel partially filled with single ...
Multi-Stage Hybrid Loading Fatigue Life Prediction Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue is a damage accumulation process in which material properties are continuously deteriorated and degraded under cyclic loading. Damage accumulation analysis plays a key role in preventing the occurrence of fatigue ...
Study of Time Resolved Vortex Structure of In Cylinder Engine Flow Fields Using Proper Orthogonal Decomposition Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The structure of incylinder flow field makes significant impacts on the processes of fuel injection, air–fuel interactions, and flame development in internal combustion engines. In this study, the implementation of ...
Fatigue Damage of Aluminum Alloy Spot-Welded Joint Based on Defects Reconstruction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional (3D) reconstruction and finite element method are combined to study the damage behavior of aluminum alloy resistance spot-welded joints. Fatigue damage of spot-welded joints under different cyclic loading ...
Fatigue Damage Study of Steel–Aluminum Friction Stir Welding Joints Based on Equivalent Damage Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An equivalent damage model was established to study the fatigue damage behavior of steel–aluminum friction stir welding (FSW) joints. Internal defects of friction stir welding joint under various cyclic loading stages were ...
Recent Progress on the Tribological Applications of Solid Lubricants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonrenewable energy has produced abundant waste during tribological applications because a large portion of energy has been consumed to overcome friction and wear. Solid lubricants have recently aroused significant interest ...
Experimental Investigation of the Variations of Early Flame Development in a Spark Ignition Direct Injection Optical Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments under two intake air swirl levels (swirl ratios of 0.55 and 5.68) were conducted in order to investigate the early flame development of combustion in a singlecylinder sparkignition directinjection engine. The ...
