Modeling and simulation of the horizontal seat suspension system under random vibration

Abstract

The paper presents a procedure for creating a simulation model of the horizontal seat suspension system. At first, the physical model is proposed and then the non-linear characteristics of individual system components are described mathematically. The unknown model parameters are determined by means of the specific experiments that are performed in laboratory conditions. Finally, the vibration transmissibility behavior is investigated ensuring that the created simulation model is as close to the real vibro-isolation process as possible. The results of numerical research and experimental investigation are discussed in view of their potential interest in the development of vibration isolation systems used for protecting the human body against harmful vibrations. The proposed model should support the selection process of system components that significantly affect the vibro-isolation properties of horizontal seat suspensions.
