摘　　要：在能量法的基础上推导了杆系结构的动力稳定度判定准则,运用本课题组自主研究的压电摩擦阻尼器的各种参数,并提取参数运用到结构体系中。通过在单层网壳结构中设置压电摩擦阻尼器,利用稳定度判定准则分析了没有压电阻尼器和嵌有压电阻尼器的网壳结构的动力失稳特性。结果表明:结构动力稳定度能量判定准则能够有效地判别结构动力失稳的时刻,能直观的分析结构各个状态的参数。判定过程方便,判定结果直观,并且说明压电阻尼器能有效抑制网壳结构的振动响应。Based on Various parameters energy method, this paper derives dynamic stability judgement criterion of bar system structure. ofpiezoelactric fiction damper developed independently by our topic team were extracted and used for structural system. Through setting piezoelactric friction damper in single layer reticulated shell structure and on the basis of stability judgement criterion, the dynamic unstability characteristics of reticulated shell structure with and without piezoelactric damper were analyzed. Results show that the energy judgement criterion of structural dynamic stability may judge structural unstability moment effectively and analyze the parameters of structure visually in each state. The judgement has convenient process and visual result. It illustrates that the piezoelectric damper may reduce reticulated shell structural vibration response.
