“Buckling Analysis of Tie Rod of a Tractor and Its Optimization”

Mechanical Engineering

A tie rod is a slender structural rod in the automobile steering system and it is capable of carrying tensile and compressive loads. Tie rod may fail due to compressive loads through buckling. Instability of vehicle may be caused due to failure of tie rod. So it’s important to check the strength of tie rod. The load on tie rod is mostly compressive. In this paper we are going to do the finite element analysis of the existing tie rod of the tractor and will compare those with the FEA results of optimized tie rod. All the measures will be taken to improve the strength of the tie rod. 3D modeling of a tie rod is done in CATIA V5R19. Further, meshing and analysis is done on HYPERMESH (preprocessor) and ANSYS (postprocessor). Optimization of the tie rod will be carried out in iteration with topological changes. Optimized tie rod will be analyzed through FEM. After getting satisfied results a prototype will be fabricated and tested. The two results i.e. FEA and experimental results will be validated.
