摘　　要：采用旋转流变仪、橡胶加工分析仪、压缩生热试验机、回弹仪测试胎面胶的动态能量损耗,针对应变、应力、能量3个因素建立了各测试方法的简易应变/应力-时间数学模型,探讨论胎面胶的动态能量损耗与损耗因子(tanδ)的相关性。结果表明:旋转流变仪和橡胶加工分析仪都是恒定应变测试,二者测试的胎面胶的tanδ相关性较好;压缩生热试验机是恒定应力测试,测试的胎面胶的动态能量损耗与tanδ成正比、与模量成反比;回弹仪是接近恒定能量测试,测试的胎面胶的动态能量损耗与tanδ成正比;轮胎的滚动阻力指数与胎面胶的tanδ线性相关性较好。The dynamic energy loss of tread compound was measured by rotary rheometer,rubber processing analyzer,compression heat build-up tester and rebound instrument.Based on the three factors of strain,stress and energy,a simple mathematical strain/stress-time model of each test method was established,and the relevance of dynamic energy loss and loss factor(tanδ) of tread compound was discussed.The results showed that,both rotary rheometer and rubber processing analyzer provided constant strain tests,and the tanδof the tread compound measured by these two methods had a good correlation.The compression heat build-up tester provided a constant stress test.Under this condition,the dynamic energy loss of the tread compound was proportional to tanδ and inversely proportional to modulus.The rebound instrument provided a near constant energy test,and the dynamic energy loss of the tread compound was proportional to tanδ.In addition,the rolling resistance index of the tire showed a good linear correlation with the tanδ of the tread compound.
