铸铁制动盘自1953年以来就已在日本的列车制动中应用，但在运用中存在耐磨性和热裂方面的一些问题，因此自1975年以来又开发了一些其它种类的制动盘材料。1990年闸片材料由石棉复合材料改为非石棉复合材料，最近各种各样的制动盘和闸片都在应用，因此，对某些制动盘和闸片的摩擦磨损特性作出评定是十分重要的。我们对不同的制动盘和闸片的组合进行了高速摩擦试验和台架试验，并研究了其基本的摩擦磨损特性。
Cast iron brake discs have been used in Japan’s train brakes since 1953, but some problems with wear resistance and hot cracking exist during use. As a result, some other types of brake discs have been developed since 1975 material. In 1990, the brake lining material was changed from asbestos composite material to non-asbestos composite material. Recently, various brake discs and brake discs were used. Therefore, the friction and wear characteristics of some brake discs and brake discs were evaluated Very important. We conducted a high-speed friction test and a bench test on different brake disc and brake disc combinations and studied their basic friction and wear characteristics.
