Semi Exact Natural Frequencies for Kirchhoff–Love Plates Using Wave Based Phase Closure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents semiexact, closedform algebraic expressions for the natural frequencies of Kirchhoff–Love plates by analyzing plane waves, their edge reflections, and their phase closure. The semiexact nature is such ...
Damping Frame Vibrations Using Anechoic Stubs: Analysis Using an Exact Wave-Based Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper explores the addition of small stubs with anechoic terminations (termed herein “anechoic stubs”) as a means of damping and/or removing vibration modes from planar frame structures. Due to the difficulties ...
Dynamic Programming Informed Equivalent Cost Minimization Control Strategies for Hybrid Electric Vehicles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a direct mathematical approach for determining the state of charge (SOC)dependent equivalent cost factor in hybridelectric vehicle (HEV) supervisory control problems using globally optimal dynamic ...
Two-Scale Command Shaping for Reducing Powertrain Vibration During Engine Restart
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper introduces a two-scale command shaping strategy for reducing vibrations in conventional and hybrid electric vehicle (HEV) powertrains during engine restart. The approach introduces no additional system components ...
Higher-Order Dispersion, Stability, and Waveform Invariance in Nonlinear Monoatomic and Diatomic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies have presented first-order multiple time scale approaches for exploring amplitude-dependent plane-wave dispersion in weakly nonlinear chains and lattices characterized by cubic stiffness. These analyses have ...
Belt-Drive Mechanics: Friction in the Absence of Sliding
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Recent studies have shown that steady and unsteady operation of a belt drive may exhibit regimes absent of sliding at the belt–pulley interface, where instead detachment waves serve to relax stress in the so-called “slip” ...
Schallamach Wave-Induced Instabilities in a Belt-Drive System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We experimentally study the dynamic behavior of a belt-drive system to explore the effect of loading conditions, driving speed, and system inertia on both the frequency and amplitude of the observed frictional and rotational ...
Experimental Verification of Pulse Shaping in Elastic Metamaterials Under Impact Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present experimental verification of pulse shaping in elastic metamaterials together with a procedure to design, fabricate, and verify metamaterial pulse shapers under impact excitation. The split Hopkinson pressure bar ...
Analysis and Experimental Estimation of Nonlinear Dispersion in a Periodic String
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wave dispersion in a string carrying periodically distributed masses is investigated analytically and experimentally. The effect of the string's geometric nonlinearity on its wave propagation characteristics is analyzed ...
