Aiming at the defects of narrow band of traditional dynamic vibration absorbers,a new type of variable mass negative stiffness dynamic vibration absorber was presented,so that the vibration absorber might have a good low-frequency efficiency.Firstly,the dynamic equation of the variable mass negative stiffness vibration absorber was established and the operating principles of the absorber were analyzed.Secondly,the variable mass negative stiffness vibration absorber experimental table was built,while the PID...
