摘要
时速350km/h高速列车在紧急制动过程中将产生巨大的热负荷,制动过程中闸片的瞬时温度将达到900℃以上,在此极端工况下普通的闸片材料将难以胜任。根据UIC标准相关要求,结合中国高速列车的运用特点,研制出一种性能优良的高速列车铜基粉末冶金闸片,经大量试验研究分析最终证明所研制高速动车组粉末冶金闸片摩擦性能优良、导热性、耐磨性好,对制动盘无损伤,满足350km/h高速列车制动系统相关需求。
Great heat load was generated in an emergency brake process while a high speed train runs 350 km/h. The transient temperature of brake pad was up to 1 000℃. The normal brake pad can not competent for the task under such an extreme condition. In this ar- ticle, according to the requirements of the UIC standards and Chinese Specific characteristics of railway operation, a kind of high performance powder metallurgy copper-based brake pad was designed after extensive study. This kind of brake pad possesses high property, good thermal conductivity, good abrasion resistance and not damage brake disc. It completely meets the requirements of the brake system of high speed train which has a top speed of 350 km/h.
