The paper establishes the finite element calculation model of the bulldozer’s tooling structure. Taking the D85A-18 bulldozer’s tooling as an example, the example calculation is carried out. Comparing with the experimental data, it shows that the method has high calculation accuracy and efficiency, as well as strong versatility. It provides a universally applicable method for calculating the structural strength of various types of bulldozers.
