Effects of the Nature of Excitation on the Response of a Mistuned Bladed Disk Assembly
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, responses of a mistuned bladed disk assembly are examined and compared for three types of excitations: uncorrelated narrow band random excitations, correlated narrow band random ...
Statistics of Response of a Mistuned Bladed Disk Assembly Subjected to White Noise and Narrow Band Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the statistics of the response of a mistuned bladed disk assembly subjected to random excitation. Analytical techniques are developed to compute this statistics for two ...
Computation of the Optimal Normal Load of a Friction Damper Under Different Types of Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, forced responses of a frictionally damped turbine blade are investigated for three different types of excitation: white noise excitation, narrowband random excitation, and deterministic ...
Mitigating Vibration Along an Arbitrarily Supported Elastic Structure Using Multiple Two-Degree-of-Freedom Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Simple spring-mass systems are often deployed as vibration absorbers to quench excess vibration in structural systems. In this paper, multiple two-degree-of-freedom oscillators that translate and ...
Using a Characteristic Force Approach to Determine the Eigensolutions of an Arbitrarily Supported Linear Structure Carrying Lumped Attachments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper a characteristic force approach is developed that can be used to determine the eigenvalues and mode shapes of any arbitrarily supported linear structure carrying various lumped ...
Vibration Localization by Disorder in Assemblies of Monocoupled, Multimode Component Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Disorder in nominally periodic engineering structures results in the localization of the mode shapes to small geometric regions and in the attenuation of waves, even in the passbands of the ...
Frequency Analysis of a Linear Elastic Structure Carrying a Chain of Oscillators
Publisher: American Society of Civil Engineers
Abstract: In this technical note we analyze the free vibration of
Applying Sherman-Morrison-Woodbury Formulas to Analyze the Free and Forced Responses of a Linear Structure Carrying Lumped Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple approach is proposed that can be used to analyze the free and forced responses of a combined system, consisting of an arbitrarily supported continuous structure carrying any number ...
Eigenfrequencies of an Arbitrarily Supported Beam Carrying Multiple In-Span Elastic Rod-Mass Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many vibrating mechanical and structural systems consist of a host structure to which a number of continuous attachments are mounted. In this paper, an efficient method is proposed for determining ...
Enforcing Nodes to Suppress Vibration Along a Harmonically Forced Damped Euler-Bernoulli Beam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, properly tuned damped absorbers are used to suppress excess vibration anywhere along an arbitrarily supported, damped Euler-Bernoulli beam during forced harmonic excitations. This ...
