Research and Application of Standardization for Mechanical Analysis of Nuclear Power Equipment

摘要

In the design of nuclear power equipment, the traditional mechanical analysis is finite element modeling, loading, calculating and post processing by writing a personalized APDL command stream or operating ANSYS GUI according to the design standards and personal analysis experience. And the operation of ANSYS graphical interface is cumbersome and complex, resulting in low efficiency of modeling, large amount of work. By the command stream, the workload of modifying calculation file is large and the command code is plain, which is not conductive to the standardization of the analysis process, and easy to make human error, miss parameter modification and error modification commands, causing the analysis result to appear serious mistake. In view of the deficiency in the process of mechanical analysis, this paper takes the axisymmetric penetration of nuclear power equipment as the research object, based on the software engineering technology, using the technology of ANSYS secondary development, puts forward a standardized method to reduce human error, improve the accuracy and usability of mechanical analysis, and develops the mechanical analysis platform for axisymmetric penetration. The platform helps designers through a simple interface to quickly and efficiently complete the calculation and analysis of axisymmetric penetration, which unified the calculating process, reach the precipitation and sharing of the experience, improve the accuracy, reduce the workload of manual operation, enhance the work efficiency and provide practical experience for the popularization and application of standardization in verification and analysis of other nuclear power equipment.
