The Society of Automotive Engineers organizes student design competitions to inculcate in students the general practices of good Engineering. One such student design activity is the SAEINDIA BAJA event held each year in Pithampur, India the aim of which is to build an All Terrain Vehicle as per the constraints given by the organizers. The growing popularity of the competition coupled with the need to design safe, sturdy and sustainable ATV has led to the origin of the idea of the paper. The process of dynamic stress analysis is expensive and time consuming, and simulating the problem statement is unnecessarily tedious at an initial design stage. So it is advantageous to carry out the static stress analysis first, which offers a simplistic simulation criterion of the problem statement and requires a lower computational time. This analysis will validate the safety of the preliminary design and help the designer understand the changes that need to be incorporated in the design. The paper aims to give an introduction to this static stress analysis method using ANSYS APDL 12.0, covering topics such as impact force determination, loading points, convergence of nodes, and the mesh size dependence of generated stress.
