Mechanical, mechatronic and adaptive technologies for the stabilization of beam-columns and truss structures (C02)

桁架结构轴向载荷下梁柱屈曲突然破坏的不确定性可通过主动稳定或主动屈曲控制来控制。采用压电弹性支承实现了单梁柱的主动屈曲控制。轴向载荷时变的多梁柱网络控制影响着SFB-demonstrator等大型桁架结构的整体动力性能。单个桁架部件的故障以及不可预见的几何形状或动力学变化都可以通过主动技术进行补偿。

Uncertainty of sudden failure due to buckling of axially loaded beam-columns in truss structures is con-trolled by active stabilization or active buckling control. Active buckling control of single beam-columns is achieved by piezo-elastic supports. Network control of multiple beam-columns with time-varying axial loads influences the global dynamic behavior of larger truss structures such as the SFB-demonstrator. Failures of individual truss components as well as unforeseen changes in geometry or dynamics over time are compensated by the active technology.
