Design and Development of a High Speed and High Rotation Robot With Four Identical Arms and a Single Platform
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a novel parallel kinematic mechanism (PKM) with Schأ¶nflies motion has been proposed under the guidance of a graphical type synthesis method. This PKM is composed of four identical arms and a single platform ...
On the Assessment of Through-Wall Circumferential Cracks in Steam Generator Tubes With Tube Supports
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The assessment of steam generator tubes with defects is of great importance for the life extension of steam generators. Circumferential through-wall cracks are the most severe of all tube ...
Fracture Healing Properties of Asphaltic Material under Controlled Damage
Publisher: American Society of Civil Engineers
Abstract: The self-healing properties of asphalt materials present a new means to achieve reliable, durable, and sustainable asphalt pavements through maximizing the effect of microdamage recovery. However, healing (healing of ...
An Investigation of Magnetic Pulse Welding of Al/Cu and Interface Characterization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigated the effect of magnetic pulse welding (MPW) condition (welding power, surface scratches, and contamination) on the establishment of welding between aluminum and copper tubes, and the associated welding ...
Computational Analysis of a Inverted Double-Element Airfoil in Ground Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow around an inverted double-element airfoil in ground effect was studied numerically, by solving the Reynolds averaged Navier-Stokes equations. The predictive capabilities of six turbulence ...
Prediction and Recovery of Aircraft Unstable Nonlinear Phenomena Using Bifurcation Analysis and Backstepping Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To protect the aircraft flight safety across the envelope of angle of attack, bifurcation analysis and backstepping method are investigated to predict and suppress the unstable nonlinear flight phenomena. By applying ...
Influence of Diffuser Angle on a Bluff Body in Ground Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The forces and pressures on a generic bluff body in ground effect were investigated. The bluff-body model was equipped with interchangeable underbody diffuser ramps and side plates. Five different ...
Computational Analysis of Pressure and Wake Characteristics of an Aerofoil in Ground Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pressure and wake of an inverted cambered aerofoil in ground effect was studied numerically by solving the Reynolds-averaged Navier-Stokes equations. Efforts were focused on the setting up ...
Generalized Method to Analyze Acoustomechanical Stability of Soft Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic radiation force generated by two counterpropagating acoustic waves in a thin layer of soft material can induce large deformation, and hence can be applied to design acoustomechanical actuators. Owing to the ...
A Two-Level Model for the Wind- and Buoyancy-forced Circulation
Publisher: American Meteorological Society
Abstract: The classic theory of deep circulation by Stommel and Arons is extended to a two-level model. Instead of specifying the interfacial upwelling a priori, it is calculated as part of the solution. The model shows strong ...
