Traction optimization method suitable for trolley vehicles

Abstract

The invention discloses a traction optimization method suitable for trolley vehicles, which comprises the following steps: initializing the starting acceleration of the tram, the starting speed of a constant power characteristic region and the starting speed of a reduced power characteristic region; According to the starting acceleration, the initial speed of constant power characteristic zone andthe initial speed of reduced power characteristic zone, the traction characteristic curve of tram is drawn. The optimal traction characteristic curve of the tram is obtained by optimizing the traction characteristic curve with the starting acceleration constraint, the residual acceleration constraint, the maximum torque constraint, the maximum power constraint and the average acceleration constraint. Otherwise, the process proceeds to step S3. A technical scheme of that invention aim at solving the problem that the traction scheme of the EMU is directly applied to the tram due to the existence of the running vehicle clothes between the EMU and the tram at present, An optimization algorithm for tram traction is specially designed, which reconstructs the constraint interval of tram and optimizes the tram traction.

Description

technical field [0001] The invention belongs to the field of traction movement of rail trains, and in particular relates to a traction optimization method suitable for trams. Background technique [0002] With the development of my country's urbanization process, large and medium-sized cities are adjusting their industrial structures and expanding urban areas; through the development of the main central area and sub-central area of ​​large cities, the development of satellite towns and other aspects to re-plan each city, the huge size of large cities Space range and traffic demand make it increasingly dependent on traffic. Urban transportation is changing from supporting services to a determinant factor guiding the development of large cities. At the same time, due to the constraints of resource factors such as land, energy, and road network capacity, rail transit has been recognized as the development direction of urban transportation by countries all over the world. It pl...
