Simulation Analysis of Influence of Skeleton Material on Stiffness of 245/40ZR17 Passenger Car Radial Tire
Taking 245/40ZR17 passenger car radial tire as the research object,the finite element simulation method was used to study the effects of belt cord angle,belt cord density,carcass polyester cord specification,and crown strip winding method on the tire's stiffness.The results showed that the radial stiffness of the tire was affected by belt cord density mostly,followed by the belt cord angle.The crown strip winding method and the belt cord angle had a significant impact on longitudinal stiffness of the tire.Increasing the belt cord angle would reduce the tire's longitudinal stiffness,while increasing the amount of crown strip winding could improve the tire's longitudinal stiffness.Increasing the belt cord angle would increase the tire's lateral stiffness,while the strength of the carcass cord had a certain impact on the tire's lateral stiffness but showed a non-correlation.The crown strip winding method had the greatest impact on the tire's torsional stiffness,and the S-shaped tire shoulder thickening crown strip winding method had the smallest torsional stiffness of the tire.
