Abstrait:

Due to high vibration sensitivity of ultra-light structures, active vibration control is required in future applications. To demonstrate the efficiency, a multi-modal active vibration control system was developed and implemented for a stress ribbon footbridge at Berlin Institute of Technology. Initially, the control design for the above mentioned stress ribbon footbridge based on an analytical plane rigid body model. But with increasing complexity of the structure analytical modelling becomes a challenging task. In this paper the potentials of using reduced finite element models for model-based design of active vibration control are investigated. For the example of the stress ribbon footbridge modal reduction is applied to a 2D and 3D finite element model. Results by means of the transfer behaviour between the actuator input and sensor output are compared to the existing experimentally validated analytical model and show good agreement. Hence, the reduced finite element models are suitable for model-based design of active vibration control. As proof, simulations show that the active vibration control delivers good results.
