Based on the calculation method of the elastic modulus of the metal ring element, the formula for calculating the elastic modulus of the metal rubber ring vibration isolator is derived and verified by experiments. Through the analysis of a large number of experimental results, the relationship between the average stiffness, internal friction and energy dissipation coefficient of metal rubber annular vibration isolator and the diameter of wire, geometric parameters of annular vibration isolator and the relative density of metal rubber components . Based on the formation principle of elastic hysteresis loop, the mathematic model of elastic hysteresis loop of this kind of vibration isolator is established and verified by experiment. With the help of the mathematical model and the finite element method, the elastic damping performance of any metal rubber ring vibration isolator can be obtained directly, which greatly reduces the experimental workload.
