Global Sensitivity Analysis of the Vibration Reduction System with Seated Human Body

Abstract EN

The paper deals with the global sensitivity analysis for the purpose of shaping the vibroisolation properties of suspension systems under strictly defined operating conditions.

The variance-based method is used to evaluate an influence of nonlinear force characteristics on the system dynamics.

The proposed sensitivity indices provide the basis for determining the effect of key design parameters on the vibration isolation performance.

The vibration transmissibility behaviour of an exemplary seat suspension system is discussed in order to illustrate the developed methodology.
