Study of the Modeling Method of Diesel Locomotive's Transmission System Based on System Identification

Abstract

Diesel engine is the source of power for the entire transmission system, it is used mostly step control, the engine gear position and speed is a one-to-one correspondence, regard the diesel engine's speed as the engine's control the amount of input, the different position of the internal combustion engine gear will cause it to run at different speeds. Establishment of the relationship between the locomotive diesel engine speed and the locomotive speed is of great significance to predict the speed of the locomotive and guide the driver the rational manipulation. In this paper, DF7G diesel locomotive will be the object of study, and we will study how to build the transmission system model of the diesel locomotives.
