Modeling and simulation of hydraulic system for a wheel loader using AMESim

Advancement of simulation capabilities made it possible to simulate any physical system before building the prototype to evaluate controls and performance test of components. Simulation results help to improve the design, reliability and operability, thereby reducing cost and time associated with the design significantly. This paper presents a simulation modeling way which used by software AMESim of hydraulic system for a wheel loader that represents a large family of machines. The simulation program is developed by modeling each component of wheel loader hydraulic circuit such as main pump, main control valve (MCV), compensator, joystick and attachments according to their specifications. Simulation runs are carried out using this model with various external conditions encountered in real working environments. At the end simulation results are presented to show the performance of the developed model. The results of simulation as compared with experimental results are nearly consistent, which proves the model is right and thereby the wheel loader performance can be determined.
