技术领域 Technical field

背景技术 Background technique

The actual gap becomes smaller and the brake blade is hug. At the same time, the friction particles on the brake disc are regular hexagon and the gap is small. The metal grinding material generated during the braking process and the hard particles from the outside cannot be discharged in time to form the metal inlay. The crystal nucleus is directly involved in grinding the brake disc, resulting in abnormal wear of the brake disc.
目前，世界各国尤其高寒地区的国家（主要包括北欧、俄罗斯、日本等）均采取了类似的措施，主要为融冰除雪、降速运行、减少冰雪天气动车组的使用频率。以下为北欧（瑞典）、俄罗斯、日本冬季车辆采取的措施： At present, countries in the world, especially in the alpine regions (mainly including Northern Europe, Russia, Japan, etc.) have taken similar measures, mainly for melting ice, removing snow, slowing down the operation, and reducing the frequency of use of ice and snow weather EMUs. The following measures are taken for winter vehicles in Northern Europe (Sweden), Russia, and Japan:
（ 1 ）北欧（瑞典）融冰除雪措施 (1) Nordic (Sweden) ice melting measures
北欧针对冬季冰雪天气，主要进行线路除雪，配备专门的除雪机车，将路基上的积雪清除到路边。同时，线路上配备融冰除雪装置，使用加热的丙二醇对基础制动装置进行除冰。 For the winter snow and ice weather, the Nordic countries mainly carry out snow removal on the roads and equipped with special snow removal locomotives to remove the snow on the roadbed to the roadside. At the same time, the line is equipped with a melting ice removal device, and the base brake device is de-iced using heated propylene glycol.
（ 2 ）俄罗斯融冰除雪措施 (2) Russia's ice-melting measures
在冰雪天气严重时，库内配备热水融冰除雪装置，使用低压热水对基础制动装置进行除冰。 When the snow and ice weather is severe, the warehouse is equipped with a hot water melting ice removal device, and the base brake device is de-iced using low-pressure hot water.
（ 3 ）日本融冰除雪措施 (3) Japan's ice-melting measures
在冰雪天气严重时，线路上配备热水融冰除雪装置，使用热水进行除冰。 When the snow and ice weather is severe, the line is equipped with a hot water melting ice removal device, and hot water is used for deicing.
综上所述，动车组基础制动装置结冰积雪引起的制动盘异常磨耗问题是世界性难题，主要通过除雪、配备融冰除雪设备或采用限速（含停运）等外部措施应对冰雪天气，这些方案需要大量的人力、物力、财力，增加 检修维护工作量及运营成本。 In summary, the abnormal wear of the brake disc caused by the icing and snow accumulation of the EMU base brake device is a worldwide problem, mainly through external measures such as snow removal, equipped with ice melting and snow removal equipment or using speed limit (including outage). Ice and snow, these programs require a lot of manpower, material resources, and financial resources. Overhaul maintenance workload and operating costs.
