Electrode replacement is an effective method to extend the useful lifetime of the spark gap switch with graphite electrodes. In order to perform electrode replacement, suppressing temperature rise and preventing static welding/erosion should be considered for the static electrical contact interface between the electrode and the holder. In this paper, a mathematical model of contact temperature rise...
In this paper, the free vibrations of incomplete toroidal shells with different meridional boundary conditions are studied based on the linear Flugge thin shell theory. The cross-section of toroidal shells is assumed to be a closed circle. The circumferential modes are represented by a series of trigonometric functions and the meridional modes are expressed as a combination of beam functions which...
The component mode synthesis (CMS) technique has been widely used in engineering for its efficiency in dynamic analyses. The principle of CMS with fixed interfaces is introduced, the detail steps in calculation are summed up, and the flow chart of algorithm is also given. The dynamic properties of elastic tube bundles are investigated with the application of CMS. The effect of numbers of nominal modes...
