| 摘要:以两种常用的船舶橡胶隔振器为研究对象,通过调整不同的试验条件,进行了隔振器的静态和动态特性试验研究。研究表明:静态性能影响因素按影响大到小,分别为加载速率、预压次数、加载时间间隔；而对动态性能,激励位移的增大或预加载荷的减小,均使得动刚度-频率曲线有整体下降的趋势。 |

| Abstract:Research was carried out on two widely-adopted marine rubber isolators. Experiments were done under different conditions to study the static and dynamic performance of these two isolators respectively. The experiment results shows that, for static performance, the influencing factors are loading rate, preloading times and loading interval, with the influence decreases in order; whereas for the dynamic performance, the dynamic stiffness-frequency curve descends when exciting displacement increases or preloading decreases. |
