Method for carrying out finite element parametric modeling on triangular grid stiffener cylinder structure

The invention provides a method for carrying out finite element parametric modeling on a triangular grid stiffener cylinder structure. According to the invention, the method for carrying out parametric modeling on the triangular grid stiffener cylinder structure is established and is realized by using MSC (Mobile Switching Center).PCL (Pinter Control Language) programming, modeling parameters comprise seven parameters of height H of a cylinder, external radius R, covering thickness t, circumferential grid number n, rib crossing angle theta, rib height h and width w, a finite element analysis model can be quickly established by any combination of the seven parameters on the premise that reasonable combination is met, and the time for carrying out modeling on a daily microcomputer is about five seconds through actual measurements. The method provided by the invention has the advantages of high modeling automation level, quick speed, good element mass and high analysis accuracy; high-accuracy and fast-optimization analysis on the triangular grid stiffener cylinder structure can be realized by matching optimization design software such as Isight.
