【摘要】 实验研究了由钢丝绳隔震器组成的爆炸冲击隔震系统在爆炸冲击下的响应及破坏机理,得到了爆炸冲击隔震系统的破坏模式;通过对比实验得到隔震系统效果的定量认识;最后用快速傅里叶变换对结果进行分析。结果表明:隔震系统能够比较显著地减弱低频振动的幅值,这对于结构减振有积极的意义,可以在爆炸塔等爆炸试验场所推广应用。更多还原

【Abstract】 The response and failure mechanism of a PGG damping system was studied with tests.According to test results,the failure pattern of the system and the quantitative cognition for the shock absorption effect of the system were found.At last,the test results were analyzed in frequency domain with FFT.The results indicated that the damping system is very effective for shock absorption in structures under blast shock.更多还原
