It's a crucial issue to elevate the adhesion capacity of locomotive, with the accretion of the traction charge of electrical locomotive caused by the construction of high speed railway in all of the countries, especially the implementation of the strategy of 'high speed and over loading' in China.For the first time, this paper builds a favorable co-simulation platform between ADAMS/Rail-MATLAB/Simulink for the study of locomotive adhesion control method. The locomotive mode built here is more precise than intrinsic dynamic analysis and approaches better to real locomotives. The feasibility of this platform is tested by realizing the anti-slide/slip adhesion controls for the mode on complex rail conditions, adopting the basic theory and methods of locomotive adhesion control. The chief study work as follows:Based on the detail mechanical structures and dynamic condition of locomotive and its dynamic condition, the assembly and subsystems for a locomotive in the Standard Interface are built based on templates of running gears, car body and auxiliary devices built in Template Builder; several force and torque parameters are designed. What's more, the harmonization of initial value are verified by running the preload analysis, and also the dynamic analysis is functioned by choosing some appropriate rail conditions and rail-wheel contact modes. It's more precise to describe the locomotive system by building a locomotive virtual mode in ADAMS Virtual Prototype.The co-simulation between ADAMS and MATLAB brings to success via ADAMS/CONTROLS after defining the Inputs and Outputs in ADAMS and also defining some relative parameters in the control system structured in MATLAB.After the definition of three different rail conditions, the platform is validated and by applying and comparing hybrid adhesion control method and fuzzy control method on locomotive anti-slide/sip control simulations. The results are satisfying because of the success on anti-slide/slip controls, elevating traction force and ameliorating locomotive function condition.Co-simulation of locomotive adhesion control is a field of multi-subjects. The result data becomes more credible because of the build of ADAMS locomotive virtual mode. The favorable platform realized by ADAMS-MATLAB co-simulation can more accurately show the control impacts of different adhesion control methods, which brings faster regulations and modifications to adhesion control methods and also mechanical structural designs. Comparing with intrinsic physical prototype test, the economical cost and test cycle are both reduced by co-simulation.The success of anti-slide/slip control of locomotive on complex rail conditions verifies the platform and provides the possibility for questing optimal adhesion control methods.This paper is a foundation for further study of adhesion control methods in our lab.
