This paper shows the static strength analysis of the tractor front axle housing by using of the finite element analysis software ANSYS, visually shows equivalent stress and strain distribution and vertical displacement distribution of the front axle housing. At the same time it also shows the analysis results of the model processing, the results of accuracy and reliability, and the weak links of the structure. By analyzing the weakest link and the difference in strength between each node for the overall structure in the condition, it can provide a direction and theoretical basis for the design and optimization of geometric entities. And the results of the analysis may be as the basis for structural improvement. In this way, it can be verified that using computer virtual software for product development is positive.
