Development of Dual-power 48 Grinding Stone Rail Grinding Trains

Abstract

Abstract: Three technical implementation routes of the dual-power 48 grinding stone rail grinding trains were analyzed, and the technical route of the trains adopted by “diesel generator set + overhead contact system + AC drive” was determined, then the key technologies of the trains were listed. The main structures and performances of the trains were introduced, and the traction characteristics were calculated and analyzed under the self-running conditions and grinding working conditions respectively. Finally, the railway adaptability, product advantages, social benefits and test conditions of the trains were described. The calculation analysis and test results show that the traction characteristics of dual-power 48 grinding stone rail grinding trains meet the working requirements on long steep grades, and the trains adapt to the existing passenger line of various speed grades, the strength of car bodys and bogies, the dynamics performance and the working performances all meet the requirements of test standards. The trains also have the advantages of energy saving and environmental protection, and are suitable for tunnel grinding.

Key words: dual-power, rail grinding train, independent research and development, electric drive
