Proofs (Cont’d) Introduction Hysteretic models Identification methodology Future work Experimental identification Summary Proof. Step 3 θ(x) demonstration Then its derivative dθ(x) = k wρ(1 − w(x)) dx Defining a = k wρ and b = ρ, the derivative can be rewritten as dθ(x) = a − ρθ(x) dx Return Arturo Rodríguez Tsouroukdissian Small-scale MR dampers for vibration mitigation
Small-scale technical data Introduction Hysteretic models Identification methodology Future work Experimental identification Summary Technical data of the small-scale MR friction controllable damper LORD Corp. Stroke = 58 mm, Weight = 0.48 Kg, Input current = 0.5 A (continuous) and = 1 A (intermittent), Resistance (ambient temp.) = 20Ω Operating temperature = 70 C Damper forces (peak-to-peak) = 100 N (5 cm/sec @ 1 A) and = 2 N (20 cm/sec @ 0 A) Disadvantage → do not apply more than 0.5 A for longer than 30 sec at a time, or heat buildup may melt the plastic shaft. Wonder Box → device to control the MR damper. Power supply = 12 V DC and 2 A DC, the PC voltage signal is from 0 to 5 V DC, and the output current is from 0 to 2 A DC.
