| Abstract: | This paper focuses on a new designed 20-meters bridge-inspection vehicle. The whole vehicle is modeled within Pro/e software with respect to four kinds of working conditions, and its static and modal finite element analysis are performed by using the finite element code ANSYS. Based on these analysis results, the strength of the whole designed structure is checked, and all dangerous parts are found, finally, some suggestions are given to strengthen the structure. The finite element analysis is an important theoretic method to verify the design, and the results provide theoretic bases and technological support for this vehicle design and manufacture. |
