RISA Theory for the Articulation of Planar Robots: Part I—Kinematic Analysis for the Flexure and the Parallel Operation of Robots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is the first of a series of papers developing a theory for the articulation of planar robots. Here, end effectors are considered to be moving on specified trajectories regardless ...
A Theory for the Articulation of Planar Robots: Part II—Motion Planning Procedure for Interference Avoidance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a motion planning procedure for planar robots which provides the robots with abilities to change flexure (i.e., to articulate) and hence to avoid interference with other ...
Transient Response of Submerged Plates Subject to Underwater Shock Loading: An Analytical Perspective
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, Taylor’s floating air-backed plate (ABP) model is extended to the case of a submerged water-backed plate (WBP) within the acoustic range. The solution of the WBP is cast into ...
Fluid-Structure and Shock-Bubble Interaction Effects During Underwater Explosions Near Composite Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There is an increasing interest in the use of composites for marine/naval structures to reduce weight and maintenance cost, and to improve hydrodynamic and/or structural performance. In particular, ...
A Numerical Tool for the Design/Analysis of Dual-Cavitating Propellers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The motivation of this work is to develop a numerical tool to explore a new propeller design with dual-cavitating characteristics, i.e., one that is capable of operating efficiently at low ...
Numerical Simulation of Solitary Waves Using Velocity–Vorticity Formulation of Navier–Stokes Equations
Publisher: American Society of Civil Engineers
Abstract: This paper presents the development of a novel numerical scheme to study solitary wave phenomena using velocity–vorticity formulation instead of the primitive variable (velocity-pressure) form for the Navier–Stokes equations. ...
Dynamic Hydroelastic Scaling of the Underwater Shock Response of Composite Marine Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hydroelastic scaling relations for the shock response of water-backed, anisotropic composite marine structures are derived and verified. The scaling analysis considers the known underwater ...
Three-Dimensional Underwater Shock Response of Composite Marine Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, there has been an increased interest in the use of advanced composites in marine applications. It has been shown that by exploiting the inherent anisotropic nature of the ...
A BEM for the Prediction of Unsteady Midchord Face and/or Back Propeller Cavitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A boundary element method (BEM) is used for the numerical analysis of sheet cavitation on a propeller subjected to the non-axisymmetric wakes of marine vehicles. This method is extended in ...
Capacities of Template-Type Platforms in the Gulf of Mexico During Hurricane Andrew
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper details results from nonlinear analyses of the ultimate limit state performance characteristics of four Gulf of Mexico (GOM) platforms subjected to intense loadings from hurricane ...
