RISThe Prediction of Substructure and System Modes by the Extended Complex Mode Indication Function
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Yee and Tsuei (1989) developed the Modal Force Technique (MFT) as a tool for component synthesis. The approach utilizes the frequency response functions at connecting joints to predict the ...
Transient Response by Component Modal Synthesis Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for determining the transient responses of a system is introduced. This method is an extension of the component modal synthesis technique. The transient responses of the system are ...
Free Boundary Problem for the Laplace Equation With Application to ECM Tool Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tool design problem of electrochemical machining (ECM) is formulated by the inverted approach in which the spatial coordinates are treated as the dependent variables on the plane of the ...
A Central Crack in a Finite Rectangular Plate With Four Hinged Edges Under the Opening Mode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By combining linearly the Fourier transform and Fourier series, the stress intensity factor of a central crack in a finite rectangular plate with four hinged edges under the opening mode is ...
A Method for Modifying Dynamic Properties of Undamped Mechanical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for the parametric study of the eigen frequencies and eigen vectors of a dynamic system is presented. The technique is based on the force response of the original dynamic system and ...
Adaptive Control of Above Knee Electro-Hydraulic Prosthesis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conventional designs of an above-knee prosthesis are based on mechanisms with mechanical properties (such as friction, spring and damping coefficients) that remain constant during changing cadence. ...
Investigation of a Turbulent Radial Wall Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper measurements are presented of mean velocities, turbulence intensities, Reynolds’ stresses, and the wall friction in a radial wall jet formed by an impinging circular jet on a ...
Extraction of Normal Modes from Contaminated Measurement With Noise for Highly Coupled Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A frequency-domain technique to extract the normal mode shapes from the contaminated FRF measurements for highly coupled structures is developed. The relation between the complex FRFs and the ...
Estimation of Mass, Stiffness and Damping Matrices from Frequency Response Functions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A frequency-domain method for estimating the mass, stiffness and damping matrices of the model of a structure is presented. The developed method is based on our previous work on the extraction ...
Experimental Study on Vibration of a Rotating Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The vibration of a rotating blade is investigated in this work. A rotor system is built and natural frequencies of the rotating blade are measured and compared with the numerical results from ...
