Dynamic Loading and Stress Analysis of Tank Track Pad using Finite Element Method

Abstract

Structural analysis is important for analyzing any structure for stability under all types of loadings. It determines the deformational behavior of structure and helps in realizing the life of structure. Finite element analysis is a numerical method used in this work for structural analysis of an armored tank track pad. Pak Army is in the continuous indigenization process, endeavors to reduce reliance on imports. A heavy fleet of armored main battle tanks are part of Pak Army. Modern armored tanks and other tracked vehicles use track pads to reduce vibrations, noise, road damage and to provide better traction. These track pads undergo frequent failures due to abrasion, chunking, deep cuts and scooping etc. The premature failure of these pads increases the import bill. The material and shape play a significant role towards life of the track pad. In this research work, finding a better track pad design for armored tracked vehicles is targeted. The work involves stress analysis through finite element method. Static structural analysis is performed with compressive loadings and dynamic analysis for constant speed operation is performed with compressive and shearing forces. Focus is laid on stress reduction by changing materials and varying shape. Four types of materials and seven different shapes are compared through finite element analysis. A better design of track pad is suggested as outcome at the end of the work which proves that the original design is not an optimized design.
