This article proposes an analytical methodology for the optimal design of a magnetorheological (MR) valve constrained in specific volume. The optimization method is to identify geometric dimensions MR valve, and determine whether performance has undergone major improvement. Initially, enhanced radial structure with effective annular composite flow paths was designed. After describing schematic configuration operating principle proposed mathematical model pressure drop derived on basis Bingham fluid. Sequentially, multi-objective problem had been formulated constructed approximate exploiting NSGA-II algorithm find global optimum geometrical valve. Meanwhile, influences variables were analytically investigated by mapping finite element analysis numerical responses response surface techniques. Lastly, experimental test rig setup explore dynamic time initial as well controlled cylinder system under different excitation conditions. results revealed that applied current 1.6 A, power consumption improved significantly values 4.46 MPa 16.84 W, respectively, when compared 4.03 27.65 W their respective values. Additionally, average efficiency 14.29%, its value being 81 ms 94.5 ms. Moreover, damping force valve-controlled 4.34 kN, which 12.44% larger than one 3.86 kN at A.
