摘要
对动力机器-基础-地基动力相互作用(Structure Soil Dynamic Interaction,SSDI)体系进行了建模分析。在此基础上,通过现场动力测试和试验模态分析对该体系进行了动态参数识别和工作性能评价,获得了体系振动特性,探讨了引起机组故障的原因。最后,总结了诊断结果并提出了实用可行的加固处理建议。
An analysis model for machine - foundation - subgrade dynamic interaction system （ Structure Soil Dynamic Interaction, SSDI） was established. On this basis, through dynamic field＇ test and modal analysis, the dynamic parameter identification and working performance evaluation were carried out, the system vibration characteristics were obtained and the cause of machine set fault was discussed. Finally, the diagnosis result was summarized and suggestions for practical and feasible reinforcement treatment were put forward.
