摘要

Seismic isolation is one of the best options to protect equipments. It helps to control response accelerationrntransmitted to equipment under its allowable level. Among several type of isolation system, therncombination of restoring spring and slider (resilient sliding system) is a very effective system forrnprotection of equipment. In design of this type of isolation system to ensure functions of equipments, therernare many suitable combinations of stiffness and friction coefficient. However at the same time it is alsornnecessary to control relative displacement of isolation system so as to provide safety to the connections ofrnequipment with other systems like power supply, main servers etc. This study deals with optimum designrnof equipments with these resilient sliders that may control acceleration under allowable level and at samerntime minimize the relative displacement. Optimum parameters of resilient sliding isolators are determinedrnanalytically for different levels of allowable acceleration. The validity of analytical method used, is alsornverified by shaking table tests. Results of this study show that 1) Optimum values of period are decreasedrnwith growth of allowable acceleration and 2) The optimum friction coefficient is increased with higherrnallowable acceleration.
