Research on the Low-frequency Mechanical Characteristics of MR Damper in Ship Isolator

Abstract

In this paper, by using the fast response, controllable isolator system. In this paper, a series of characteristics curves damp, small consume, wide dynamic scope, great adaptation of of MR damper are obtained through the vibration experiment the MR damper, a new isolator composed of steel rope spring and on isolator system. According to the experimental results, the MR damper is designed and a study on the low-frequency relations of damping force and its influencing factors are mechanics characteristics of MR damper in isolator is carried out, analyzed and some useful conclusions are obtained, which is then the relations between MR damping force and other factors very significant to practical application of MR damper on ship.are analyzed with experimental data, it shows that damping force not only has something to do with structural dimension, but also is related to controllable current and vibration frequency. Finally, II. EXPENRIMENTAL PLAN the experiential formula of damping force is corrected and the In this paper, the ship isolator is designed to study the relations between corrected coefficients and factors are obtained. mechanical characteristics of MR damper, it makes sense to practical application of isolator .To solve this problem, a new Keywords-ship isolator; maganeto fi dship isolator composed of traditional vibration absorber and low-frequency; mechanical characteristics power component in parallel is presented as shown in Figl, of which the dynamic characteristics can be controllable, so that it
