RISEquations of Motion of Dynamical Systems From Kinematic Characteristics of the Phase Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the analysis of most engineering dynamical systems, relativistic considerations are unnecessary, allowing an absolute time and simultaneity of events to be assumed. In this article, it is first established that this ...
Resolving Absorbed Work and Generalized Inertia Forces From System Energy Equation—A Hamiltonian and Phase-Space Kinematics Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops a theoretical basis and a systematic process for resolving all inertia forces along generalized coordinates from the overall energy equation of a dynamical system. The theory is developed for natural ...
Transient Response of Linear Systems Under Integral Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The requirement of satisfying an integral constraint imposed on a linear system's transient step-response is considered in this paper. The problem is first analyzed to determine the specific structure of a system's transfer ...
An Adaptive Observer for Recirculation Based Solid Oxide Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present an observer design for online estimation of species concentrations in recirculationbased solid oxide fuel cell (SOFC) systems with integrated reformers. For the system considered, onboard reforming ...
Reconfiguration of a Rolling Sphere: A Problem in Evolute-Involute Geometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides a new perspective to the problem of reconfiguration of a rolling sphere. It is shown that the motion of a rolling sphere can be characterized by evolute-involute geometry. ...
Effect of Integral Feedback on a Class of Uncertain Nonlinear Systems: Stability and Induced Limit Cycles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The theoretical problem addressed in the present work involves the effect of integral feedback on a class of uncertain nonlinear systems. The intriguing aspects of the problem arise as a result of transient constraints ...
Equilibrium Behavior of a Tethered Autogyro: Application in Extended Flight and Power Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, we study the characteristics of steady autorotation of a tethered autogyro. The phenomenon of autorotation refers to the natural spinning of a rotor in a wind field. We explore the viability of tethered ...
Effects of Total Pressure Distribution on Performance of Small-Size Counter-Rotating Axial-Flow Fan Stage for Electrical Propulsion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Counter-rotating fan provides significant benefits over the conventional fan in terms of overall performance and size. For electric propulsion application, a counter-rotating fan provides compactness and reduction in weight ...
Control Oriented Modeling, Experimentation, and Stability Analysis of an Autorotating Samara
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a control-oriented model for describing the steady-state and dynamic behavior of a single-winged samara seed-pod in autorotative descent. A negligible lateral center of mass motion and constant, prescribed ...
Steady-State and Transient Analysis of a Steam-Reformer Based Solid Oxide Fuel Cell System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we perform a model-based analysis of a solid oxide fuel cell (SOFC) system with an integrated steam reformer and with methane as a fuel. The objective of this study is to ...
