Modeling, Nonlinear Dynamics, and Bifurcation Analysis of the Rotor–Seal System Using a Subharmonic Sampling Strategy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotors are used to transfer power from one component to the other component in various rotor dynamics applications like steam turbines, aerospace systems, and power generators. In certain applications, the seal is an ...
A Simple Configuration of an Actively Synthesized Gyroscopic-Nonreciprocal Acoustic Metamaterial
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple configuration of an active nonreciprocal gyroscopic metamaterial (NGMM) is presented. In the proposed NGMM system, a one-dimensional acoustic cavity is provided with piezoelectric boundaries acting as a collocated ...
Computation and Assignment of the Minima of Structurally Radiated Sound Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The minimum sound pressure is an important aspect of noise control. This means that minimal or no noise at a location will be experienced at a certain frequency. In many engineering applications, it is desirable to compute ...
Dynamic Analysis and Design of Metamaterial Plates With Crossed Acoustic Black Holes for Vibration Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic black holes (ABHs) have shown great potential in vibration and noise control. Merging the ABH effect and the metamaterial can be a more efficient approach for vibration control. The aim of this article is to study ...
Equivalent Beam Model and Improved Structure Design of Large Space Antenna Truss With Geometric Nonlinearity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a extend linear equivalent method that can extend the linear equivalent micropolar beam model to the nonlinear equivalent micropolar beam model to analyze nonlinear vibration for large space truss ...

Efficient Hybrid Symbolic-Numeric Computational Method for Piecewise Linear Systems With Coulomb Friction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A wide range of mechanical systems have gaps, cracks, intermittent contact or other geometrical discontinuities while simultaneously experiencing Coulomb friction. A piecewise linear model with discontinuous force elements ...
Stability Analysis of Nonlinear Rotating Systems Using Lyapunov Characteristic Exponents Estimated From Multibody Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of Lyapunov characteristic exponents to assess the stability of nonlinear, time-dependent mechanical systems is discussed. Specific attention is dedicated to methods capable of estimating the largest exponent without ...
Non-Smooth Dynamics of Tapping Mode Atomic Force Microscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examines the nonlinear dynamics in tapping-mode atomic force microscopy (AFM) with tip-surface interactions that include van der Waals and Derjaguin-Müller-Toporov contact forces. We investigate the periodic ...
Stability and Bifurcation Analysis of Precision Motion Stage With Nonlinear Friction Isolator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The application of servocontrolled mechanical-bearing-based precision motion stages (MBMS) is well-established in advanced manufacturing, semiconductor industries, and metrological applications. Nevertheless, the performance ...
