Application Research On Visualization Modeling Technology In Hydraulic Pressure CAI Simulation Experiment

Hydraulic simulation technology plays an important role in the design, analysis and optimization of Hydraulic system. It has been widely recognized in the relevant engineering field. According a lot of excellent dynamic simulation software of hydraulic system has emerged. As one of hydraulic pressure simulated software, hydraulic pressure CAI teaching simulation software is a kind of tool that is specially used for the computer-assisted teaching. Upon the progress of computer technology, it has been developing quickly. As a modern teaching tool of hydraulic lesson, Hydraulic CAI is taking more and more important role in the hydraulic teaching practice.From the view of application of the system simulation, using visual interactive modeling environment and objected-oriented technology to reduce the time of modeling and improve the communication between person and computer has become one of the hot-point of simulation technique.This paper carries out the research on the visual dynamic modeling environment of hydraulic systems and its key techniques. Feature-based technology and object-oriented technology will be combined into the graphical modeling software development; establishing an open graphics storehouse based on the characteristics of the hydraulic components; establishing graphical user interfaces which can enable users to draw hydraulic system diagram and through the graphics interface to realize the system simulation and automatic modeling function of the hydraulic principle diagram. This paper proposes and establishes a visual modeling environment based on graph and object-oriented technology .in the comparative analysis based on the schematic diagram of hydraulic modeling method through the use of hydraulic diagram modeling, integration of computer graphics technology and object-oriented modeling technique, established a clear hierarchy of hydraulic components and hydraulic components entities class model bank, thus achieving better integration of map scale. Use data structure theory, artificial intelligence theory, Fig. modeling technology etc. to realize following functional module: the abstract and definition of hydraulic element, the construction, automatically identifying, storing and system simulation of hydraulic system, and some hydraulic CAI simulation experimental modules.
