RISThe Response of an Oscillator With Bilinear Hysteresis to Stationary Random Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By applying the technique of stochastic averaging, a simple analytical result is obtained for the joint distribution of the displacement and velocity of a bilinear oscillator excited by a ...
First-Passage Time for Oscillators With Nonlinear Damping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple numerical scheme is proposed for computing the probability of first passage failure, P(T), in an interval O-T, for oscillators with nonlinear damping. The method depends on the fact ...
Probability of First-Passage Failure for Nonstationary Random Vibration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of calculating the probability of first-passage failure, Pf , is considered, for systems responding to a short pulse of nonstationary random excitation. It is shown, by an analysis ...
Energy-Based Stochastic Estimation for Nonlinear Oscillators With Random Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A physically based averaging procedure is applied to a general form of a nonlinear single-degree-of-freedom equation, with nonwhite random excitation, leading to a one-dimensional continuous Markov ...
Local Similarity in Nonlinear Random Vibration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A response analysis procedure is developed for oscillators with highly nonlinear stiffness and light nonlinear damping excited by non-white wide-band random noise based on local similarity between ...
Observations on the Nonlinear Fluid Forces in Short Cylindrical Squeeze Film Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent theoretical work by Tichy and Bou-Said (1991) and El-Shafei and Crandall (1991) has resulted in new theoretical expressions for the nonlinear inertia forces for both short and long ...
Pressure Distributions in a Superlaminar Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The main features of a comprehensive set of pressure measurements, obtained from a short, plain journal bearing, are presented. The pressure field in the lubricant film was measured in both ...
An Experimental Study of First-Passage Failure of a Randomly Excited Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Some experimental measurements of the mean and standard deviation of the first-passage time of randomly excited cantilevers are presented. It is shown that these results can be predicted ...
Experimental Behavior of a Short Cylindrical Squeeze Film Damper Executing Circular Centered Orbits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The experimentally determined behavior of a short radial squeeze-film damper with no end seals, executing circular centered orbits, is discussed. Accurate circular orbits were achieved, for ε ...
Force Coefficients for a Centrally Grooved Short Squeeze Film Damper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A centrally grooved short squeeze film damper (SFD), together with its lubricant supply mechanism (LSM), is analyzed, using an integrated theoretical model. It is shown that the traditional ...
