- 摘要:
- 在参考目前海洋平台损伤检测方法的基础上,应用固有频率的损伤检测方法,以频率变化量与频率之比为参数,结合JZ20-2MUQ平台的相关检测数据,对该平台进行了损伤诊断和初步的安全评估。对损伤诊断和安全评估结果的深入分析验证了固有频率损伤检测方法的可行性。
With the reference to current offshore platform damage detection methods,the natural frequency method is adopted for the damage diagnosis in this paper.It takes the ratio of frequency variation value to frequency as the parameter and combines with the quantitative test data of JZ20-2MUQ platform to perform the damage diagnosis and preliminary safety assessment of the platform.The analysis on the damage diagnosis and safety assessment results validates the feasibility of the natural frequency method.2013,4(4): 20-22 收稿日期:2013-2-26DOI:10.3969/j.issn.1001-2206.2013.04.005基金项目:国家863资助项目“基于振动检测的现役海洋平台结构安全评估技术研究”(2008AA092701)作者简介:颜昌德(1983-),男,湖南衡阳人,工程师,2008年毕业于哈尔滨工程大学结构工程专业,硕士,主要从事海洋工程结构设计和海洋平台检测及安全评估的工作。参考文献:
