The Study Of Parametric Modeling And Finite Element Analysis System For The Structure Of Hydrogenation Reactor

Hydrogenation reactor is the key equipment in the hydrogenation unit of the oil refining industry. It usually works in the environment of high-temperature and high-pressure which is very harsh. And there is big mechanical stress and thermal stress in the operation, which related to the safety of the entire device. Therefore, hydrogenation reactor's designed and manufacturing requirements are too strict, so the safety of it must be guaranteed. However, the current work of design and analytical are mainly rely on manual, which is so repetitive and inefficient. In order to improve the design level and efficiency of the hydrogenation reactor, the paper have made a systemic study to the hydrogenation reactor and draws up practical parametric finite element analysis software by using finite element method and parametric further-development technology.The system is characterized by the object serialization and functional diversity. This system can complete the mechanical stress analysis, temperature field analysis, thermal stress analysis, comprehensive stress analysis, stress assessment and optimal design of the the skirt supporting zone for the bubble-cap tower and the float valve tower. And it also can finish the finite element analysis on the structure of opening reinforcement and non-reinforcement structures. At the same time, a aided design module is also added to this system.This paper discusses the nesting-technique between APDL of the ANSYS'second developing tool and VC++. The method and interface functions for VC++ called ANSYS were also studied. It established a friendly interface of human-computer interaction, completing the process of generating APDL batch code files automatically through extracting the input parameters of interface. And this system make use of VC++ to encapsulate APDL, then it can automatically read the APDL orders into the ANSYS to complete the finite element analysis which instead of the method of GUI in human-computer interaction. This avoid the information lose in the process of the conversion between the modeling and analysis and promote the working efficiency and the reliability of modeling and finite element analysis. At last, take the structure of opening reinforcement for example to complete the system demonstration which verified the feasibility and correctness of the system.
