| Abstract: |
| A kinematic simulation study was conducted on the stepped direct-pressure vulcanization
inner mold（referred to as the stepped inner mold） of 225/40R18 tire. By setting the connecting rods and
motion pairs，as well as using the STEP function to control the movement of the inner mold，the displacements
of observation points set at the center positions of the piston outer rod，piston inner rod，wide drum tile and
narrow drum tile were obtained through the simulation. The results showed that the movement of the stepped
inner mold were smooth and continuous without interference. |
