Nonlinear dynamics of asymmetric bistable energy harvesters

The paper investigates asymmetries effects over a nonlinear vibration energy harvester dynamics. asymmetric system performance is compared with symmetric ones. Different asymmetry levels on restoring force and gravity action are investigated from system-sloping angle variation. Bifurcation diagrams basins of attraction used to examine the local global characteristics underlying dynamical systems under different excitation energy. results show adverse They also reveal ways overcome them by canceling influence optimal sloping values improving symmetrical This comprehensive numerical study provides novel valuable insights into asymmetrical dynamics, wide still less explored topic.
