At present China's railway passenger turnover finished sending cargo , cargo turnover , converted turnover ranking first in the world . Railway technological innovation has improved significantly , made a series of technological innovations in the high-speed railway , the plateau railway , heavy transportation and other fields , marking the overall technological level of China's railway advanced in the world , and to achieve the export of high-speed rail technology. With the rapid development of high -speed rail technology , and how to improve its security design various research institutes have become urgent technical problems to overcome .
It is understood the train braking and friction braking is broadly divided into non- friction brake , brake friction include : air brake , wheel brake , braking track . Non- friction include : dynamic braking , regenerative braking, the braking resistor ( used mainly aluminum braking resistor resistor ) , eddy current braking . In terms of today , although there are trains using regenerative braking and air brake combined composite braking mode , regenerative braking takes precedence , and the gap supplemented by air brake , and the maximum possible braking power to play the role . However, non- friction brake application is still limited by the current situation and the basic design of the vehicle . Therefore, the current emergency braking friction generally considered the most effective way of braking is a more universal and practical application of braking .
With the rapid development of high-speed rail in the country , braking resistor ( aluminum resistance ) promotion will be able to improve the safety performance of vehicles belonging to the invention of new technology and practical , on behalf of our increasingly innovative high-speed rail technology. Advent track complex emergency brake assist devices for higher speed trains escort , creating a new era of high-speed rail safety .
