Abstract
This paper presents multimode vibration absorbing methods which employ negative resistance (NR) and negative inductance negative resistance (NINR) electromagnetic shunt damping vibration absorbers. The NR and NINR shunts can change the impedance of an electromagnet so as to change the control force of the absorber. The governing equation of the coupling system is established. What is more, some numerical simulations are carried out and the results show that the absorbers with NR or NINR shunt can effectively suppress the multimode vibration. Furthermore, the root locus is analyzed to design the resistance of a shunt.
