摘要:

提出了一种实用的新型含压电堆材料的主元杆件,阐述了其应用于钢结构稳定控制的基本工作机理,讨论了该主元杆件在不考虑机电耦合及考虑机电耦合时的极限承载力的改变,同时运用有限元法,讨论了压电主元杆件中含压电堆的长度对其静力稳定性的影响,并进行了数值计算。结果表明:考虑机电耦合能够显著提高主元杆件的极限承载力; 主元杆件所含压电堆的长度对静力稳定性的影响并非线性提高,而是必须在特定的刚度优化时才能进行有效地控制。

Abstract:

A new type of pivot element bar included piezoelectric stack material was proposed. Its applicability and suitability for the stability control of steel structure were also expressed. Basic mechanical performances of the piezoelectric spar element under cases of electromechanical coupling and electromechanical decoupling were considered with related structure mechanical theory. At the same time, influence of the length of the piezoelectric material included in the smart active spar element on static stability was quantitatively analyzed by numerical calculation. The results show that the ultimate bearing capacity will increase obviously if considered the electromechanical coupling effect; influence of the length of the piezoelectric material included in the smart active spar element on the stability behavior dose not linearly increase, only in a certain stiffness optimization, the control might be effective.
