Dynamic Response of a Semiactive Suspension System with Hysteretic Nonlinear Energy Sink Based on Random Excitation by means of Computer Simulation

Figure 5

Responses of displacement of the half vehicle system while the excitation is bump road inputs. The vector represents the displacements of the driver U5, the chassis U4, and the pitch angle U3, i.e., , respectively. Simulation period T = 10 seconds, sampling interval h = 0.01 seconds, vehicle velocity  = 1.1256 m/s (the time delay ) and (b) same as (a) except for the vehicle velocity  = 20 m/s (the time delay ).
