Optimal Design of Magnetorheological Damper Based on Tuning Bouc Wen Model Parameters Using Hybrid Algorithms
This paper presents a useful approach to optimally design magnetorheological (MR) dampers used in structural buildings. To fulfill this aim, damper parameters are regarded as the design variables whose values can be obtained through an optimization process. To improve the quality of searching for the optimum parameters of MR dampers, charged system search (CSS) and grey wolf (GW) algorithms, two of the most widely utilized meta heuristic algorithms, are used together, and hybrid CSS GW is presented. To show the authenticity and robustness of the new algorithm in solving optimization problems, some benchmark test functions are tested, at first. Then, an eleven story benchmark building equipped with 3 MR dampers is considered to get the optimum design of the MR damper using the hybrid CSS GW. Results show that the developed hybrid algorithm can successfully figure out the optimum parameters of the MR dampers.
