Abstract: Metal-net rubber is a porous material composed entirely of metal wire woven. Compared with the traditional spiral coiled metal rubber material, the molding technology of metal-net rubber material is improved, which eliminates a large number of manual process interferences in preparation process. The metal-net rubber material has higher mechanization degree, better coincidence and more stable mechanical properties. With the excellent characteristics of bearing capacity, large damping, high temperature resistance, low temperature resistance, aging resistance, oil and corrosion resistance, metal-net rubber material is better than traditional rubber in many ways, which is widely used in aerospace, shipbuilding, military weapons and other military industries. Spring metal-net rubber combination damper has designable stiffness and high bearing capacity. Because of its complex nonlinear hysteresis characteristics, the constitutive model of related materials is difficult to describe its mechanical properties accurately. Based on the static hysteresis mechanical performance experiment of spring metal-net rubber combination damper, combined with the hysteresis characteristics of dry friction damping, a theoretical modeling model of hysteresis mechanical properties is proposed. According to the characteristics of restoring force-displacement curve of damper hysteresis experiment, the hysteresis curve is decomposed into elastic recovery force and dry friction damping force by parameter separation method. The equivalent stiffness and dry friction damping coefficient are solved respectively by modeling to establish the theoretical model of the combination damper. By comparing with the experimental results, the error analysis is carried out to verify the accuracy of the theoretical model.
