Abstract:

The Army is planning to upgrade the existing Main Battle Tank. Concern was expressed whether the current lifting configuration was strong enough to support the additional load of this upgrade. A non-linear finite element analysis of four different configurations was done to determine whether the front lifting eye was strong enough. The analysis indicates that with a spreader bar incorporated in the lifting harness, the eye is strong enough. Without such a spreader bar, a detailed comparison between competing strengthening configurations was made. Additional welds were as strong as full penetration welds. The recommendation was to strengthen the lifting eye by using the additional welds proposed by the Abrams Project Managers Office
