摘 要:本文介绍动态摩擦系数测试仪(DynamicFrictionTester,简称DFT)的原理、构造和测试方法,在大量对比试验的基础上对DFT、横向力系数测试车(SCRIM)以及摆式摩擦系数测试仪之间的相关性进行了分析。最后,作者对DFT在中国的应用提出了自己的看法。In China, the typical equipements to test the friction coefficient of highway pavement are SCRIM and Portable Friction Tester. However,a new type equipment, Dynamic Friction Tester (DFT) is introduced in this paper including its principle,structure and method. It is found that DFT has many advantags in pavement friction test. The test results have good stablility and high repeatability. To compare DFT with SCRIM and Portable Friction Tester, a great deal of tests have been carried out and the data have been studied well. The correlative is analyszed and a regression formula with a good correlation is estalished. Finally the view point about the appilcation of DFT in China is put forward.
