Abtract:With the increasing number of tasks and the shortening of development cycle, the traditional pressure vessel design analysis model has been unable to meet the requirements of analytical tasks for time and accuracy. Based on parametric modeling, CAD/CAE two-way parameter driving and flow encapsulation of analysis process, three types of pressure parametric models with different topological structures are established. The two-way parameter driving between design and simulation is realized. Models can be generated and simulated automatically and the result can be extracted. Besides, a pressure vessel intelligent simulation tool is developed. It is found that the intelligent simulation tool is able to shorten analysis cycle and improve the efficiency and quality of the simulation.
