Abstract

The invention discloses a method for analyzing the strength and the stability of a C-shaped tunnel pipe by applying finite element software. Based on C-shaped tunnel pipe limit load analysis, characteristic value buckling analysis and nonlinear buckling analysis, the invention aims to provide software for automatically finishing the strength and the stability analysis of the C-shaped tunnel pipe and outputting an analysis result. The software uses an APDL language in ANSYS to compile a corresponding algorithm program, and combines a VB language to carry out secondary development on ANSYS software. A software program interface is simple and easy to operate, and structural design of the C-shaped tunnel pipe is facilitated. A user can perform finite element analysis on the C-shaped tunnel pipe through the software to evaluate the influence of different structural parameters on the strength and stability of the C-shaped tunnel pipe, so that the analysis process of the C-shaped tunnel pipeis simplified, and a reference basis is provided for optimization of the size structure of the tunnel pipe.

Description

technical field [0001] The invention relates to a method for analyzing the strength and stability of a tunnel pipe, in particular to a method for analyzing the strength and stability of a C-shaped tunnel pipe by using finite element software. Background technique [0002] Tunnel pipes are widely used in aerospace, aviation, machinery and other industrial sectors. With the advancement of science and technology, the role and importance of tunnel pipes are increasing. There are many forms of tunnel tubes, which are divided into C, U, S, etc. according to the wave form. Among them, the C-type tunnel tube is currently widely used in the aerospace field, and the size and structure parameters of the C-type tunnel tube include wall thickness, wave height, and wave distance. Different sizes and structural parameters have different effects on the strength and stability of the C-shaped tunnel pipe. [0003] ANSYS software has powerful calculation and post-processing functions, which ...
