DESIGN AND STRUCTURAL ANALYSIS OF MILITARY VEHICLE LAUNCHED BRIDGE

Abstract

The Armored vehicle launched bridge (AVLB) is an assault bridge employed during battles.
The existing AVLB has huge capacity. However a need was identified to increase its Load bearing
capacity above with higher factor of safety while engaged in military operations. This report presents the
improved design of AVLB. The Sections installed in design promotes high moment of inertia and
stiffness which makes it resistant to bending moment. The web of Sections provides resistance against
shear force. In this project work has been taken up on the different aspects of Materials like Aluminum
and Duralumin materials to cover the research gaps to present the results. The 3D Model of AVLB is
created in Catia. And finite element analysis was performed on the model of AVLB to identify the highly
stressed components of design for static structural loads. The analysis using Finite Element Method
(FEM) is used to determine shapes and this has been accomplished by the commercial finite elements
package Ansys. And all the efforts made to ameliorate the original AVLB, along with additional safety to
AVLB design by considering the factor of safety value.
