Low dynamic stiffness

In this paper, an isolator is introduced for isolating low frequency vibrations. Then, Normal form method is used to predict the curve of vibration transmissibility of this isolator. This paper is organized as follows. The mathematical model of system is presented in section.

This paper presents a low-stiffness nonlinear vibration isolator using a pneumatic spring with an auxiliary chamber which is shortened by LSNVI. Firstly, the mechanical model of the isolator, which is constructed by two opposite stiffness mechanisms includes the load-bearing mechanism (LBM) and the stiffness-corrected mechanism (SCM), is introduced.
