Two Steps of Vertical Static Stiffness Simulation Analysis of Pneumatic Ball Valve for Automobile Seat
The first analysis step: constrain the six degrees of freedom of the pneumatic ball valve, cover plate and piston of the car seat. Apply air pressure MPa (working air pressure) to inflate the pneumatic ball valve.
The second analysis step: release the vertical displacement constraint of the lower cover plate of the car seat pneumatic ball valve and keep the other freedom constraints unchanged, then apply a vertical displacement of 130mm to the upper cover plate.
Record the displacement and load data of the pneumatic ball valve of the car seat during the stretching and compression process after inflation.
