摘　　要：分析侧偏角正弦、侧偏角扫掠和稳态试验3种轮胎残余回正力矩测试方法及角度效应残余回正力矩(PRAT)的美国汽车工程师学会推荐方法和通用汽车推荐方法2种计算方法。结果表明:稳态试验方法测试PRAT的重复性最好;对于对称花纹轮胎和非对称花纹轮胎,2种计算方法的PRAT值基本无差异。In this study,three types of the test methods of plysteer residual aligning torque(PRAT)on angular effect including sinusoidal slip angle variation,slip angle sweeping and steady-state test,and two calculation methods recommended by the American Society of Automotive Engineers and GM were analyzed.The results showed that the steady-state test method had the best repeatability for testing PRAT,for symmetrical treaded tires and asymmetric treaded tires,the PRAT values of the two calculation methods were basically the same.
