Extension of backlash based dry friction model in simulink and comparison with dahl and lugre models on simulations of blade triple
Šnábl, Pavel ; Pešek, Luděk ; Půst, Ladislav
Behaviour of analytical dry friction model based on SIMULINK. Backlash block with Coulomb friction is compared with Dahl model. The Backlash based model is herein extended to contain velocity-dependent friction characteristic and is compared with LuGre model. All models are used on analytical model of blade triple with mistuned blades and vibration attenuations from first resonant mode of this system are compared. Instability of Dahl and LuGre models for large time-step are shown.
Behaviour of extended backlash based dry friction model in Simulink in comparison with Dahl and LuGre models
Šnábl, Pavel ; Pešek, Luděk ; Půst, Ladislav
Behaviour of analytical dry friction model based on SIMULINK Backlash block which was extended to contain velocity-dependent friction coefficient characteristic is studied. Comparison with the same model but with Coulomb friction characteristic and with Dahl and LuGre models is shown. Different simulation time-step is needed for each model to reach stability when increasing motion amplitude.
