Enhancing Controllability and Observability in Underactuated and Undersensed Systems Through Switching: Application to Vibration Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many dynamical systems use transducers that can function both as actuators and sensors. It is possible to continuously switch the functionality of the transducer elements in such systems and ...
Fatigue Fracture Investigation of Cemented Carbide Tools in Gear Hobbing, Part 2: The Effect of Cutting Parameters on the Level of Tool Stresses—A Quantitative Parametric Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gear Hobbing is a complex gear manufacturing method, possessing great industrial significance. The convoluted geometry of the cutting tools brings on modeling problems and is the main reason for ...
Planar Circle-Point Equations for Finitely Separated and Double-Point Positions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rigid body motion is studied for a combination of finitely and infinitesimally separated positions in planar kinematics. A general new method is developed for determining the locations of ...
Subharmonic and Chaotic Motions of a Hybrid Squeeze-Film Damper-Mounted Rigid Rotor With Active Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hybrid squeeze-film damper bearing with active control is proposed in this paper. The pressure distribution and the dynamics of a rigid rotor supported by such bearing are studied. A PD ...
Stability Analysis of a Moored Vessel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A procedure for the stability analysis of a slack mooring system is presented for periodic wave excitation by finding its approximate response using a two term harmonic balance method (HBM). ...
Comparison of the Dynamic Characteristics of Smooth Annular Seals and Damping Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Annular seals are known to enhance rotordynamic stability margins and minimize vibration response levels in high-speed rotating machinery. Theoretical predictions for the rotordynamic characteristics ...
Mixed Exact-Approximate Position Synthesis of Planar Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new approach to the synthesis of planar linkage mechanisms with fuzzy constraints is proposed. Design methods for two exact positions and an unlimited number of approximate positions are ...
