Abstract：Research purposes: With the development of railway locomotive equipment in China, especially introduction and production of new-type high-power AC driving electric locomotive-HXD locomotive. For “Shaoshan” locomotive in the operation at present, this serie of locomotive has a great improvement in tractive characteristics, locomotive power, calculating traction force and calculating speed, but under the influence of adhesion, all tractive tonnages are less than theoretical calculating value. Therefore, in this paper, it is planned to analyze the tractive tonnage of HXD freight electric locomotive and give some suggestions for revision of “Calculation Regulations on Railway Train Traction" combined with tractive characteristics of new-type high-power AC driving electric locomotive and relevant regulations in the current “Calculation Regulations on Railway Train Traction"(TB/T 1407-1998).
Research conclusions: (1) HXD electric locomotive has obvious improvement in tractive characteristics; (2) If using adhesion coefficient calculation formula in the current “Calculation Regulations on Railway Train Traction", calculating adhesion traction force of HXD freight electric locomotive is less than calculation traction force when calculating the speed; (3) The tractive tonnage calculated according to calculating adhesion traction force is less than that calculated according to calculating traction force, and the difference between different types of electric locomotives is not same and the difference of same type of electric locomotive decreases with the increase of limited slope; (4) The above study may provide some references for revision of ”Calculation Regulations on Railway Train Traction” and reasonable determination of tractive tonnage of HXD electric locomotive.
