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

• Subject Area: Lightweight Construction, Textile Technology ; Engineering Design, Machine Elements, Product Development
• Term: from 2009 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 57157498

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.
