Modelling of dynamical behavior of pneumatic spring – mass system

TranXuan T., Cirkl D.
pages 865 - 868, full text

This article deals with the simulation model of a pneumatic spring element. The purpose of this spring is to be implemented into car seat cushioning and provide a change of pressure distribution in the contact zone between seat and passenger. This function is ensured by a feedback loop controlled electropneumatic circuit. The mathematical model of the system is described by analytical functions which represent mechanical behavior of pneumatic valves, PID controller and used materials. The variable volume of the spring is considered. Dynamical response of the spring-mass system to kinematic excitation is investigated using Matlab software and transfer functions of acceleration are presented in dependence on the level of pressurization of the spring.
