摘要：
The gearbox casing's fatigue fracture is one of the most serious forms of failure in the tracked vehicle transmission system. This paper studies the fracture failure mechanism of the gearbox casing of a typical tracked vehicle by the material analysis and structural stress analysis. The results show that, the structure of the stress concentration and the organization defects such as inclusions and porosities in the Casing Material ZL101 cast aluminum alloy are the main reasons for fatigue crack initiation and propagation. This paper made recommendations on how to improve fatigue life of this kind of parts.
