RISInteractions Between Self and Parametrically Excited Motions in Articulated Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear dynamics of a two-segment articulated tubes system conveying a fluid is studied when the flow is harmonically perturbed. The mean value of the flow rate is near its critical ...
Period-Doubling Bifurcations and Modulated Motions in Forced Mechanical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Weakly nonlinear and harmonically forced two-degree-of-freedom mechanical systems with cubic nonlinearities and exhibiting internal resonance are studied for their steady-state solutions. Using the ...
Synthesis of Harmonic Motion Generating Linkages—Part I: Function Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the first and higher-order function-generation problems in the synthesis of linkages with relatively small input cranks. Such linkages tend to produce nearly simple harmonic ...
Linear Stability of Jet Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical investigation into the linear, spatial stability of plane laminar jets is presented. The three cases studied are: 1. Inviscid stability of Sato’s velocity profile. 2. Viscous ...
Bifurcations in Three-Dimensional Motions of Articulated Tubes, Part 1: Linear Systems and Symmetry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional motions of a two-segment articulated tube system carrying a fluid and having rotational symmetry about the vertical axis are examined for bifurcating periodic solutions. As the ...
Bifurcations in Three-Dimensional Motions of Articulated Tubes, Part 2: Nonlinear Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The equations of motion of the two-segment articulated tube system, discussed in Part 1, are analyzed for bifurcating periodic solutions near critical flow velocities. In addition to the flow ...
Bifurcations in Dynamical Systems With Internal Resonance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamical systems with quadratic nonlinearities and exhibiting internal resonance under periodic excitations are studied. Two types of transition from stable to unstable motions are shown to occur. ...
Evaluation of Parametric Vibration and Stability of Flexible Cam-Follower Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method to study parametric stability of flexible cam-follower systems is developed. This method is applied to an automotive valve train which is modeled as a single-degree-of-freedom vibration ...
A Preliminary Investigation of the Dynamic Stability of Flexible Manipulators Performing Repetitive Tasks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The governing equations of motion for the compliant coordinates describing a flexible manipulator performing repetitive tasks contain parametric excitation terms. The stability of the zero solution ...
Nonlinear Response of Flexible Robotic Manipulators Performing Repetitive Tasks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamics of a flexible manipulator is described by two distinct types of variables, one describing the nominal motion and the other describing the compliant motion. For a manipulator ...
