Two Steps of Vertical Static Stiffness Simulation Analysis of Electric Butterfly Valve for Automobile Seat
The first analysis step: constrain the six degrees of freedom of the electric butterfly valve, cover plate and piston of the car seat. Apply air pressure MPa (working air pressure) to inflate the electric butterfly valve.
The second analysis step: release the vertical displacement constraint of the lower cover plate of the electric butterfly valve for the car seat 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 electric butterfly valve of the car seat in the process of tension and compression after inflation.
