对渤海JZ20-2MUQ导管架式海洋平台1∶10比例模型结构进行数值分析.首先,对模型结构进行了参数影响分析,确定了隔震橡胶垫的基本参数;然后,根据阻尼器性能试验结果,确定了磁流变阻尼器的基本设计参数;最后,采用多种地震作用对模型结构进行了时程分析.结果表明:磁流变阻尼隔震控制方案有效地减少了导管架结构的振动、甲板层的加速度和隔震层的层间变形.为模型结构的试验研究提供了合理的设计参数,并验证了方案的可行性.
The 1:10 ratio model of Bohai JZ20-2MUQ jacket-mounted offshore platform was numerically analyzed.Firstly, the influence of parameters on the model structure was analyzed and the basic parameters of isolation rubber pad were determined. Then, according to the damper performance test results, The basic design parameters of the MR damper are determined.Finally, the time history analysis of the model structure is conducted by using a variety of seismic actions.The results show that the MR damper damping control scheme can effectively reduce the vibration of the jacket structure, The acceleration of the layer and the interlayer deformation of the isolation layer, which provide reasonable design parameters for the experimental study of the model structure and verify the feasibility of the scheme.
