【Abstract】 This article proposes a hydraulic system modeling language based on transmission line modeling method, elaborates on the method of using this modeling language for program implementation, and develops a system oriented graphical modeling and simulation tool. The component model based on transmission line method can be decoupled through time delay and solved in a distributed manner, and the simulation environment is suitable for distributed simulation. Numerical errors will not be introduced during simulation, and the combination of efficient simulation algorithms significantly improves design and analysis efficiency. Finally, the correctness and effectiveness of the modeling description language are verified through the simulation process of the hydraulic displacement servo system. The results indicate that the graphical modeling language based on transmission line modeling method can accurately and efficiently simulate hydraulic systems.更多还原
