摘要:
在对动力机器-基础-地基相互作用体系进行了现场动力测试和试验模态分析的基础上,对该体系进行了动态参数识别和工作性能评价; 通过现场考察和对试验数据的综合分析,获得了体系振动特性,并探讨了引起机组故障的原因; 总结了诊断结果并提出了实用可行的加固处理建议。该文的研究方法可为动力机器-基础-地基相互作用体系的动态参数识别以及机组故障诊断和处理提供参考。
Abstract:
Dynamic test and modal analysis on site for machine-foundation-subgrade interaction system were carried out. On this basis, its dynamic parameters were identified, and its working performance was evaluated. Through field research and synthesis analysis of testing data, vibration characteristics of interaction system were obtained, main causes of vibration fault were discussed. To take it further, authors concluded the diagnosis results and purposefully suggested some practical and feasible counter measures for reinforcement and rehabilitation. The analysis method can provide reference for dynamic parameter identification and fault diagnosis of machine-foundation-subgrade interaction system.
