【摘要】 通过试验,研究自主研发的压电主动杆件在单层网壳结构中的主动智能控制问题。利用集传感器、作动器和承受荷载等功能于一体的压电主动杆件,对网壳结构的地震响应振动实施主动智能控制。结果表明,这种压电主动构件作为网壳结构的内在控制源,可以有效地控制网壳结构的地震响应,起到抑制网壳振动的作用。更多还原

【Abstract】 This article studies the applications of independently developed piezoelectric active member in the active control over the lattice shell structure by experiments.Integrating the function of sensor,actuator and bearing load into one piezoelectric active member which is used to implement an intelligent active control over the seismic responses of the lattice shell structure.The results show that,as an internal control factor,this piezoelectric active member could effectively control the seismic responses of the lattice shell structure and play a role of suppressing the vibration of structures.更多还原
