Research on Simulation Experimental Teaching of Hydraulic Speed Control Circuits Based on AMESim and MATLAB

In the experimental teaching of hydraulic and pneumatic technology, AMESim simulation software and MATLAB software are introduced into the exploratory small class teaching to help students have a deeper understanding of the components, working principle and advantages and disadvantages of the hydraulic speed control circuits. Based on AMESim software, students can build, debug, run and analyze the three kinds of speed control circuits including characteristics of speed control, changes of supply pressure and ability of endurance of negative force. The comparisons between AMESim simulation results and MATLAB theoretical simulation results of speed-force characteristics are presented. And the visualization of intuitive model and simulation results can help students build other different hydraulic and pneumatic circuits, deepen their impression and understanding of the characteristics of the other circuits and make the teaching forms more diversified. Using AMESim software in experimental teaching can improve students' ability to integrate theory with practice, stimulate interest in learning hydraulic transmission knowledge and cultivate their professional ability and practical application ability.
