Analytical and experimental investigation of a high-static-low-dynamic stiffness isolator with cam-roller-spring mechanism

A high-static-low-dynamic stiffness (HSLDS) isolator using cam-roller-spring mechanism with a specially designed cam profile is proposed in this study. The proposed HSLDS isolator is mainly composed of a cam-roller mechanism (negative mechanism) and a vertical spring (positive mechanism). Different from other studies, the cam profile in this paper can be designed specially to accommodate different working requirements. Firstly, the cam design...
