The paper describes control algorithms for a combined power plant made according to a sequential scheme for a 6x6 mining dump truck. The general approaches used in the development of control systems for similar power plants and transmissions are described. The methods of testing and simulation mathematical models used to analyze the operation of control systems for combined power plants are presented. As an example of control systems, the architecture of the developed system used for a mining dump truck is given. The developed control system and simulation model make it possible to analyze the behavior of the traction motor, energy storage device, transmission elements, and operational properties.
In this article we consider one of the possible options for organizing the traction drive of a haul truck. The used scheme of the drive organization is given, and its performance is estimated by means of the drive simulation. The consideration is given to DC-to-DC converters in drives of hybrid traction systems. The conclusion is made about their influence on the efficiency of the hybrid traction drive.
The paper considers different ways of controlling the braking systems of haul trucks. The general approaches used in the development of control systems for such braking systems are described. Methods of testing and imitational mathematical models, used for the analysis of brake system control systems operation, are presented. The developed control system and the imitational model allow us to analyze the brake system behavior under different operating modes of a haul truck.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
