Abstract:

To ascertain the influence of the boundary friction on mechanical properties of disc-spring vibration isolators, a load-displacement hysteresis curve formula of disc-spring vibration isolators is derived on the basis of the energy conservation law, as well as considering the effect of the boundary friction. The formula is validated through the finite element analysis and static load tests. On this basis, the effect of the boundary friction on the bearing capacity is researched. Then the dynamic performance of disc-spring vibration isolators is studied by dynamic tests. The experimental results indicate that the boundary friction can promise a larger damping with a ratio of 0.23 for disc-spring vibration isolators. Compared with the loading frequency, the loading amplitude has a greater impact on the energy consumption, dynamic stiffness and damping of vibration isolators. This research can provide valuable information for the design of disc-spring vibration isolators.
