The number and locations of electrorheological(ER) dampers placed in the structures affect the efficiency of ER dampers in controlling the vibrations. An effective procedure for determining the number and locations of the ER dampers in complex structures was developed. Using virtual dampers placed in interested locations of the system, the energy dissipations of the virtual dampers can be (computed). According to the values of energy dissipations of virtual ER dampers placed at different (positions), the search procedure for the best locations of ER dampers is discussed. Using the presented method, a numerical example of a vehicle structurer is given in this paper. The results obtained (indicate) that the procedure provided is valid and effective.
