Patran Based Results Processing System for Spacecraft Mechanical Analysis


Article Preview

Regarding the basic method and process of current spacecraft structural mechanics analysis, the paper used the secondary development language of Patran (PCL) to automatically extract the finite element model information such as mass property, material property, element property etc; According to the mission of spacecraft mechanical analysis, the obtained results were re-solved to get the required information. Executable program was written in Java to transform the extracted results into specific forms in accordance with the predetermined templates. Finally, using the forms and menu libraries provided by PCL language, graphical interfaces were created to integrate all the functions and procedures in to Patran so that the whole process could be accomplished through an intuitive graphical interface, which was user-friendly. Adoption of the result processing system on specific examples verified the feasibility of the system.
