摘要
提出两种测试方案对橡胶材料的阻尼比进行试验研究,通过正弦稳态扫频振动试验测试微型橡胶隔振器的隔振传递率,分析其隔振性能以及材料阻尼对振幅、频率的依赖性,为橡胶隔振器设计和应用提供依据。
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.
