Simulation of the Hydraulic Circuit of a Wheel Loader by Using the Bond Graph Technique

Hydraulic systems are widely used in Engineering because they are highly versatile and can be combined with other domains of physics (mechanics, electronics, etc.). For this reason, it is of vital importance to study and develop them with a view to obtaining mechanicalhydraulic systems that are increasingly efficient. The beginning of this paper briefly analyses the method usually used to perform simulation in the hydraulic domain. Subsequently, after performing an analysis of different Bond-Graph technique-based works, different characteristic elements will be individually analysed. Finally, the different elements analysed will be interconnected and a simulation of a hydraulic circuit will be performed in order to obtain a series of results that will enable the different rationales set out in this paper to be validated. Finally, a series of conclusions will be reached based on the work presented.
