According to CJ/T 414-2012 Technical requirements of aluminum-steel conductor rail for urban rail tran-sit,combined with the collected current process of current collectors and wear situation of aluminum-steel rail,a new abrasion test program for aluminum-steel rail is proposed based on the introduction of the abrasion test requirements and the original abrasion test program for aluminum-steel rail of the power supply system of the urban rail transit.The new abrasinon test program for aluminum-steel rail is compared and analysed with the orginal one,and verification test are carried out.The test results show that compared with the original program for the abrasion test of aluminum-steel rail,the new program's test conditions and the calculation model of the wear ratio are closer to actural applications;the direct measurement method is used to measure the height of aluminum-steel rail before and after abrasion test,and the calculated result of the abrasive ratio are more accurate and reliable.
