“…Experimental validation of NS vibration isolation mechanisms with their designs based on Euler post-buckled beams have been presented in [12][13][14][15][16]. In automotive engineering, applications include the design of NS suspensions [17,18] as well as vibration isolation seats [19][20][21] for improved passenger comfort. A highspeed railroad vibration isolation system employing NS elements was discussed in [22].…”

“…Passive vibration control of a seating system can reduce vibration by using conventional spring and damper components in the seat suspension system, but due to its characteristic limitations, vibration control that targets multiple frequencies cannot be achieved even with a well-tuned traditional positive spring-damper system. Therefore, a quasi-zero static stiffness seat suspension system based on the combination of negative stiffness and positive stiffness springs was proposed by Le and Ahn (2013) [11] to improve the vibration control efficiency of a seating system, since the characteristics of high static stiffness and low dynamic stiffness can be used to eliminate seat vibration. In [12], a poly-optimal solution was sought for a seating system combined with a pneumatic spring and damper.…”

“…This hinders the development of vertical seismic isolation systems. In recent years, negative stiffness structures (NSS) and quasi-zero stiffness (QZS) systems have been developed to overcome this disadvantage [9,10]. Nevertheless, the new approaches' applications are for the isolation of mechanical engineering only, and very limited researches focus on vertical seismic isolation.…”
