A Novel Shock Absorber with the Preload and Global Negative Stiffness for Effective Shock Isolation

Figure 17

The shock testing results of the NSA under different drop heights. (a) The drop height is 90 mm when k = 0.58 N/mm. (b) The drop height is 120 mm when k = 0.58 N/mm. (c) The drop height is 170 mm when k = 0.58 N/mm. (d) The drop height is 90 mm when k = 5.15 N/mm. (e) The drop height is 120 mm when k = 5.15 N/mm. (f) The drop height is 170 mm when k = 5.15 N/mm.
