Nonlinear vibration isolator

In the course of current research the procedure of obtaining of the piecewise linear vibration systems time and frequency responses have been developed. The method is partly analytical and partly numerical and is based on combining of linear solutions of different sections in a cycle of motion. In a row with the method of obtaining of the exact steady state time and frequency response, also it is provided sensitivity analysis of the vibration isolator.

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.

The main feature of the VSNI is that the isolated object is supported by a mechanism including wedge-roller-air spring (named the main mechanism-MM) meanwhile the model of VSNI can obtain the lower resonance frequency and the higher vibration attenuation than the equivalent linear isolation model (ELIM) but guarantee the load bearing capacity through introducing a cam-roller-air spring (named auxiliary mechanism-AM).
