Abstract

This work discusses the effects of utilizing a nonlinear energy absorber with linear and cubic stiffness characteristic in mitigating torsional vibrations in a 5 degrees-of-freedom (5- DOF) rotational system. Results comparing the effects of adding a linear TMD in the system with those obtained by adding an NES are presented which demonstrate the usefulness of an NES over a conventional TMD. Subsequently, a simpler translational system comprising of an NES is considered and an optimization-based tuning methodology is used in order to tune the NES for maximum dissipation of vibration energy. The results are compared with those obtained for the system with a linear absorber.
