RISThe Dynamics of a Harmonically Excited System Having Rigid Amplitude Constraints, Part 2: Chaotic Motions and Global Bifurcations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The simple model described in [1] was shown to exhibit nonlinear behavior such as subharmonic responses. In this paper parameter regions are examined in which no simple stable motions exist. ...
The Dynamics of a Harmonically Excited System Having Rigid Amplitude Constraints, Part 1: Subharmonic Motions and Local Bifurcations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple model for the response of mechanical systems having two-sided amplitude constraints is considered. The model consists of a piecewise-linear single degree-of-freedom oscillator subjected ...
Chaotic Motions of a Torsional Vibration Absorber
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We consider large amplitude motions of a pendulum-type centrifugal vibration absorber which is used for the reduction of torsional oscillations in rotating machinery. The basic two degree-of-freedom ...
The Dynamic Response of a System With Preloaded Compliance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We consider the dynamic response of a single degree of freedom system with preloaded, or “setup,” springs. This is a simple model for systems where preload is used to suppress vibrations. The ...
Effects of Nonlinearities and Damping on the Dynamic Response of a Centrifugal Pendulum Vibration Absorber
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear dynamic response of a centrifugal pendulum vibration absorber with damping in both the primary system and the pendulum is analyzed using the methods of harmonic balance and Floquet ...
The Dynamics of an Impact Print Hammer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model is developed to describe the characteristic behavior of an impact print hammer of the stored energy type. The armature of the impact print hammer is represented by a rigid ...
A Method for the Improvement of Impact Printer Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stored energy type of impact printer is a commonly used computer output device. It can be operated at quite high frequencies due to the fact that it has a large initial activation force. ...
A Periodically Forced Impact Oscillator With Large Dissipation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We consider the simple harmonic oscillator with harmonic excitation and a constraint that restricts motions to one side of the equilibrium position. Thus, on the achievement of a specified ...
A Subharmonic Vibration Absorber for Rotating Machinery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We demonstrate a dynamic vibration absorber system which can be used to reduce speed fluctuations in rotating machinery. The primary system is modeled as a simple rotating disk, and the idealized ...
Stability of the Unison Response for a Rotating System With Multiple Tautochronic Pendulum Vibration Absorbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to spatial and balancing considerations, the implementation of centrifugal pendulum absorbers (CPVA’s) invariably requires that the total absorber inertia be divided into several absorber masses ...
