Modelling and simulation of a fluid power didactic test rig

In nowadays world, fluid power transmission technology has become an important basic technology that cannot be replaced in modern industry, and it can be said that its application and development level has become an important symbol of the level of industrial development. Therefore, it is also very important to learn and study the principles and applications of hydraulic systems. This thesis is based on the measurement of a hydraulic teaching test rig, then using Solidworks software to draw a three-dimensional model of the system and using AMESim software to carry out computer simulations of the system. This will enable a better understanding of the considerations in the design and use of hydraulic transmission technology and a better understanding of the performance of the hydraulic system and its debugging process through computer simulations. Ultimately, it was demonstrated that the computer simulation results matched the hydraulic system test results, and that the simulation results could more accurately reflect the dynamic characteristics of the actual hydraulic system operation, which demonstrated that the digital simulation method is an effective way to analyse the dynamic characteristics of the hydraulic system. Computer simulation provides a more convenient way to analyse hydraulic systems.
