Abstract

In this paper, we studied the structural design for safety improvement of the winch mount of the armored recovery vehicle. From the finite element analysis using the safety factor of the original winch mount, the results determined that the safety factor was very low, namely 1.14 at $-15^{\circ}$ when towing the maximum force. For considering the usage and safety, the safety factor needs to increase to between 1.4 and 1.6. To improve the safety factor, a re-design, such as shape modification and strengthening the welded zone, was performed. After the improvement of the structural design, the safety factor of the improved mount was calculated at 1.78, an increase of about 56.1% from that of the original mount.
