Abstract: As the main bearer and power transmission parts of aircraft deicing vehicle, the drive axle housing should have enough strength, stiffness and good dynamic characteristics. For aircraft deicing vehicle in the form of a central hydraulic drive chassis development, the axle housing is modeled by software Solidworks and analyzed by FEM software ANSYS based on the static and dynamic theory of finite element method. Through the static analysis, modal analysis and the transient dynamic analysis for the axle housing, one can find the parts with maximum stress or deformation on the axle housing and achieve 10 order inherent frequency of its structure and corresponding model shapes. Finally, based on the results of the analysis, some improvements are put forward to increase the vertical stabilizer on one side or both sides of the axle housing.
