Download or read book Orbital Dynamics Analysis and Scale Model Testing of Galloping Transmission Lines written by Anand Gopala Krishnan and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Overhead Electrical Transmission Lines, used for carrying high voltage electrical power, are held by huge steel towers with large spans. The cables of transmission lines are subjected to three different types of wind-induced vibrations, namely, galloping, aeolian and wake-induced vibrations. During winter, in some cold climates ice is deposited on the cable, making the cross section of the cable asymmetric. When wind blows across the ice accumulated cables, they start vibrating with large amplitudes and at low frequencies. In the present work, such galloping vibrations are analyzed. Neglecting the flexural rigidity and axial rigidity of the wire, two-dimensional equations of motion of the wire are formulated. The effect of torsion of cable is neglected. Fourth-order Runge - Kutta method has been employed to solve the governing equations and to obtain the orbital motions of the transmission line cable. The analytical model includes parameters such as ice inclination angle, angle of incidence of wind on the cable, sag length, angle subtended by the relative wind velocity to horizontal and aerodynamic force coefficients. The effects of these parameters on the orbital motions of the cable are investigated. Validation of analytical studies is carried out by tests on scale models of the actual cable. The models are analyzed and the eigen values and eigen vectors are found out. Experimental investigation is carried on both the actual cable and the scaled model in the wind tunnel and orbital motions are measured. The test results are compared with the numerical simulations and discussed. The galloping motions were essentially orbital in nature. The test results validated the analytical investigations on the galloping phenomena.

This book was released on 2018-07-01 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vibration Testing and System Dynamics is an interdisciplinary journal serving as the forum for promoting dialogues among engineering practitioners and research scholars. As the platform for facilitating the synergy of system dynamics, testing, design, modeling, and education, the journal publishes high-quality, original articles in the theory and applications of dynamical system testing. The aim of the journal is to stimulate more research interest in and attention for the interaction of theory, design, and application in dynamic testing. Manuscripts reporting novel methodology design for modelling and testing complex dynamical systems with nonlinearity are solicited. Papers on applying modern theory of dynamics to real-world issues in all areas of physical science and description of numerical investigation are equally encouraged. Progress made in the following topics are of interest, but not limited, to the journal: Vibration testing and designDynamical systems and controlTesting instrumentation and controlComplex system dynamics in engineeringDynamic failure and fatigue theoryChemical dynamics and bio-systemsFluid dynamics and combustionPattern dynamicsNetwork dynamicsPlasma physics and plasma dynamicsControl signal synchronization and trackingBio-mechanical systems and devicesStructural and multi-body dynamicsFlow or heat-induced vibrationMass and energy transfer dynamicsWave propagation and testing

Download or read book Flow Induced Vibrations written by Eduard Naudascher and published by Courier Corporation. This book was released on 2012-03-27 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their variety, the vibration phenomena from many different engineering fields can be classified into a relatively few basic excitation mechanisms. The classification enables engineers to identify all possible sources of excitation in a given system and to assess potential dangers. This graduate-level text presents a synthesis of research results and practical experience from disparate fields in the form of engineering guidelines. It is particularly geared toward assessing the possible sources of excitation in a flow system, in identifying the actual danger spots, and in finding appropriate remedial measures or cures. Flow-induced vibrations are presented in terms of their basic elements: body oscillators, fluid oscillators, and sources of excitation. By stressing these basic elements, the authors provide a basis for the transfer of knowledge from one system to another, as well as from one engineering field to another. In this manner, well-known theories on cylinders in cross-flow or well-executed solutions from the field of wind engineering--to name just two examples--may be useful in other systems or fields on which information is scarce. The unified approach is broad enough to permit treatment of the major excitation mechanism, yet simple enough to be of practical use.
