摘要：

The dry friction ring-type vibration isolator is considered as an isotropic continuous medium.A method of dry friction hysteresis loop calculation is proposed based on friction force analysis of contact beam.The friction force is modeled as an equivalent distributed moment to use the finite element method(FEM)to calculate the dry friction vibration isolator hysteresis loop,so the damping characteristics can be obtained.A comparison of the hysteresis loop calculation results and the experimental results shows the average relative error is 2.7%,it proves the calculation method is feasible.
