영어 초록
This paper presents analytical and experimental investigations of a semi-active damper using magneto-rheological (MR) fluids to reduce shock and noise generated in blanket cylinder of precision printing machine. MR fluids consist of a base career fluid with m-sized iron particles in suspension. MR fluids change its apparent viscosity with an applied magnetic field and generate a fluidic resistance against flow direction. MR damper can generate a controllable damping force with high response via an apparent viscosity change. First, in this paper, a design of MR damper composed of a MR valve, an electromagnet, a spring and a piston is performed with a magnetic field analysis. Second, a prototype of MR damper is fabricated with a diameter of 72㎜ and a length of 182㎜. Third, basic characteristics on damping force are experimentally investigated and discussed.
