Dynamics and power flow behaviour of a nonlinear vibration isolation system with a negative stiffness mechanism

Significance of output:

Low-frequency vibration isolation is very challenging and nonlinear power flow behaviour is less understood. We address both challenges by investigating a nonlinear isolation system with a negative stiffness mechanism (NSM) using nonlinear power flow approach because of the traditional force or displacement transmissibility is not valid. The study clarifies the fundamental mechanisms of NSM, effectively assesses low-frequency isolation and reveal the nonlinear power flow characteristics. Adding NSM can greatly enlarge the frequency band for effective vibration isolation. The nonlinear power flow research has attracted RAE Research Exchange with China Major Award and full PhD Studentship funding of the University.
