摘　　要：针对轮胎带束层结构引起的转向残余回正力矩(PRAT)测试需要高精度专业设备,本研究基于Abaqus有限元分析软件并采用单一变量法对PRAT进行仿真分析并试验验证。多规格轮胎的分析表明:PRAT仿真结果与试验结果具有较高的相关性;在此基础上研究的轮胎断面参数、花纹沟槽角度和使用工况对PRAT影响的结果对于轮胎跑偏问题分析具有指导性。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.
