Highlights

  • An ideal inerter has been widely used in various vibration isolation fields

  • Advances in Mechanical Engineering inerter-based dynamic vibration absorbers (IDVA) were proposed by replacing the damper in the traditional dynamic vibration absorber with some inerterbased mechanical networks and significant improvement for both the HN and H2 performances was obtained in the numerical simulation

  • This article assumes that the vehicle is driving on a B-grade road, Figures 7–9 show the performance indexes and the improvement comparing to the passive suspension S0 at velocities from 5 to 50 m s–1, where S1(N), S2(N), and S3(N) represent for the suspensions involving a nonlinear fluid inerter

Summary

Introduction

An ideal inerter has been widely used in various vibration isolation fields. Due to its mechanical construction, some nonlinear properties of the inerter need to be taken into consideration. Keywords Vehicle suspension, fluid inerter, nonlinear, performance F1 = K(zu À zs) + c(z_u À z_s) + f0 sign(z_u À z_s) + b(€zu À €zs) + C1(z_u À z_s)2 + C2(z_u À z_s) fluid inerter on vehicle suspension performance, the ð9Þ spring stiffness is fixed.
