| 摘 要： | 以船用橡胶隔振器为研究对象,通过跌落试验获取了典型橡胶隔振器的冲击刚度曲线,并定量分析了预压和跌落高度对冲击刚度的影响.结果显示:相同位移下,有预压情况测得的刚度曲线比无预压情况得到的曲线其最大位移明显减小;跌落高度越高,即冲击速度越大,冲击刚度也越大.

| Abstract: | To study marine rubber isolators,the shock stiffness curves of typical rubber isolators were obtained through drop test.And quantitative analysis was carried out on the influence of preload and drop height on shock stiffness.The results show that under the same displacement,the maximum displacement of stiffness curve with preload is obviously smaller than the one without preload.And as the drop height increases,the shock speed increases,thus the shock stiffness increases too. |
