Numerical analysis has been carried out to investigate the structural characteristics of auxiliary shaft system in a compact special vehicle. Stress and deformation distributions with safe factor in the auxiliary axle system are compared. It can be seen that maximum stress happens near the local axle position and deformation at the air spring is also predicted. The results from this study could be applicable for optimal design of variable shaft system in the compact special vehicle.
