A multi-layer damper with waved plates under one-axial load is considered. A method of theoretical calculation of its energy dissipation coefficient is proposed. An experimental research of own frequencies and vibration transfer ratios for different parameters of damper structure, harmonic vibration load and random load is performed. Results of this research are approximated by functions; it is possible to use these functions for the calculation of the damper too.

Metal rubber （MR） is a kind of homogeneous poroelastic damping material made of metal wire. In this paper, by ana- lyzing the forces on the MR isolator and the MR element, the hysteresis loops of the force and deformation are studied and verified by experiments. The results show that the force and displacement hysteresis loop of the MR isolator is described by the force and deformation hysteresis loops of the MR elements. In addition, the relationship between the energy dissipation coefficient of the MR element and that of the MR isolator is derived. The energy dissipation coefficient is programmed and calculated by MATLAB using experimental data, and the results are compared with the theoretical value. It is the basis for the design and applied research of the MR isolator in a future study.

Chinese Journal of Mechanical Engineering 2005年第2期18卷 259-262页

作者： XiaYuhong JiangHongyuan HaoDegang AlexanderM.Ulanov SchoolofMechanicalandElectricalEngineering HarbinInstituteofTechnologyHarbin150001.China AircraftEnginesConstructionDepartment SamaraStateAerospaceUniversitySamara443086.Russia

Theoretical and experimental research on multi-layer steel plates isolatorare exploited. The relationship between the thickness, width, number of layers, radius, numbers ofthe rings, stiffness, inner friction force, energy dissipation coefficient of isolator are derived,and a mathematie model of hysteresis loop of isolator is obtained. Experimental results show thatthe calculation equation and mathematie model of hysteresis loop can satisfy with experimentalresults very well.
