Study On Modeling And Simulating For Pneumatic System Component

This software (AMESim) can supply users with perfect synthesis environment of simulating and flexible solution of problem so that it is broadly used in engineering study. It can use its basic elements to construct customized modules or simulation models. It has intelligent calculation modules with variable step-size, variable-order, variable type and strong robustness. It also has various simulation modes, such as: steady-state simulating, dynamic simulating, batch processing simulating, continuity and discontinuity simulating.However, its pneumatic library has very few modules, and those modules are very simple, which is quite inconvinient to use. The paper uses its two development tools, namely AMESet and AMECustom, to construct more modules for those typical components and elements that are widely used in real pneumatic systems, and more than forty submodels for pneumatic control components, actuator components and auxiliary elements are created. Conservation law of mass, the state equation for ideal gas,thermodynamic equation and flow rate equation are used to establish first order differential mathematic model, and a special investigation on mass flow rate coefficient for different components are carried out to make the model more accuarate. Some pneumatic components models are not directly made through AMESet but firstly customized and then setted to reserve more information of system and avoid possible mistakes. The models are examined through simulation test on AMESim platform, and some of them are tested by experiments, which show that the models developed in this thesis are correct and reliable.
