A new impact testing system with an integrated magnetorheological (MR) damper is proposed, and its dynamic characteristics are\nanalyzed. The testing system consists of a velocity generator, impact mass, test mass, spring, and MR damper. In order to tune the\ndual shock-wave profile, a dynamic model was constructed, and the appropriate design parameters of the MR damper were then\ndetermined to produce the required damping force. Following this, an impact testing system was constructed to evaluate the design\nanalysis and field-dependent dual shock-wave profiles. The experimental results of impact test showed that the dual shock-wave\nprofile can be altered by changing the intensity of the magnetic field
