| Abstract：As the test of ply steer residual aligning torque（PRAT） caused by the belt structure required
high-precision and professional equipment，this research carried out simulation analysis of PRAT using
the finite element analysis software Abaqus and single variable method，and gave test verification. The
analysis of various specification tires showed that the PRAT simulation results had a high correlation with
the test results. Based on this，it was found that the main factors influencing the tire PRAT were tire layout
parameters，pattern groove angles and operating conditions，and the influence of those key factors provided
valuable reference for the analysis of steering problems. |
