时速350 km标准动车组粉末冶金闸片的研究

Research of PM brake pad for 350km/h Fuxing standard EMUs

根据时速350 km"复兴号"中国标准动车组现车车况及国内使用环境多样性的特点对闸片进行配方和结构设计研究。主要研究了闸片配方中各组元成分对制动性能的影响,制动闸片的制备工艺和试验验证技术,以及装车考核中闸片的实际运用状况等。结果表明:研制的粉末冶金闸片摩擦因数稳定、耐磨性能优异、抗热衰退性好、可靠性高,满足运行使用要求。

Based on the characteristics of diversified domestic operating environment of 350km/h Fuxing standard EMUs in China, the formula and structure of the brake pad is studied , mainly involving the influence of each ingredient in the brake pad formula on braking performance, preparation techniques and test verification techniques for the brake pad and the practical application of the pad in service, etc.. Test results indicate that the newly developed PM pad exhibits stable friction coefficient, excellent wear resistance ,good resistance to thermal deterioration and high reliability, and can satisfy the operating requirements.
