• Subject Area: Lightweight Construction, Textile Technology ; Engineering Design, Machine Elements, Product Development
• Term: from 2013 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 57157498

Uncertainty in the predicted lifetime of load-carrying mechanical systems in consequence of functional impairment or collapse will be controlled by autonomous approaches of structural health monitoring and con-trol. Hence the system´s behavior is monitored and integrated actuators are used for structural control. On the one hand, uncertainty in the vibration behavior of truss structures is controlled by vibration attenuation of several beams with multiple shunted piezo-elastic beam supports. On the other hand, novel (semi-)active kinematic guidance elements are developed and investigated to control uncertainty in the load distribution of kinematically connected trusses in the SFB-Demonstrator.
