Comparative Study of Aluminum and Composite Stub Axle Using FEA

摘要

This paper includes the analysis of a front stub axle used in a rear wheel drive BAJA ATV (all-terrain vehicle). An ATV is a vehicle developed to be used on rough terrains and low traction. These types of vehicles are generally known and used for their off-roading ability and maneuverability of the vehicle on rough terrains. The stub axle used in such a vehicle is subjected to different types of loads, depending upon the motion and terrain the vehicle is running on. The analysis of the structure was compared with two different models, on the basis of their strengths and rigidity of the axle during the action of bump force subjected on the tire, change in weight of the axle and cost. This paper deals with the structural analysis of stub axle of BAJA ATV using finite element analysis approach. The objective of this analysis was to study and evaluate the performance of two stub axles made of aluminum and composite material respectively, under severe conditions.
