- Abstract
This article deals with description of simulation model of a seat with pneumatic element inserted into its cushioning. Suggested solution comprises built-in pneumatic spring with feedback control which influences the hardness of cushioning. The seat with variable cushioning properties should contribute to the increase of passenger’s comfort. In order to investigate properties of this seat-mass system the mathematical model was created and solved numerically. This model describes dynamic behavior of the electro-pneumatic mechanical system and calculates the displacement and acceleration of mass, pressure inside pneumatic spring, flow rate in controlled solenoid pneumatic valves and needed coil current in case of kinematic excitation of the seat, as well as the change of setting of desired pressure in pneumatic spring.
