Comparison of Dynamic Models of Mr Damper for Hardware in the Loop Simulation of Large-Sized Buses
TLDR
The modified hyperbolic tangent model by adopting low-pass filters was proposed and the results from the simulation showed the advantages of the modified model which were validated through HILS system.Abstract:
The present study has focused on the comparison of MR damper dynamic models for the purpose of hardware in the loop simulation. A vehicle dynamic model for large-sized bus and a control logic for MR damper was built. Two typical MR damper models, viz. Bouc-Wen and hyperbolic tangent model have been considered in this study and the advantages and disadvantages of each model on the aspect of HILS system is discussed. We discussed the limitations of each model based on the analysis of the vehicle dynamic simulation. The results showed that the existing models are not suitable for HILS system. We proposed the modified hyperbolic tangent model by adopting low-pass filters. The results from the simulation showed the advantages of the modified model which were validated through HILS system.read more
