【Abstract】 The experiments were carried out based on two proposed testing schemes for damping ratio of rubber materials.The transmissibilities of rubber microisolator were measured by sinusoidal steady-state sweep-frequency vibration experiments,and the properties of vibration isolation as well as the dependence of material damping on amplitude and frequency were analyzed.This research provided experimental basis for the design and application of rubber isolators.更多还原
