Virtual Design of Automobile Driving Axle Housing Based on ANSYS Workbench

The three dimensional geometry model of automobile driving axle housing was established by using the three dimensional CAD software UG.Then it was imported to ANSYS Workbench software.And the appropriate type of unit was selected to mesh to provide finite element model for following analysis.The structural stiffness,strength and the modal finite element analysis was carried on in ANSYS Workbench software.The simulation result indicated that the corresponding distribution of stress and deformation,whose results show that the strength and stiffness of axle housing meet the requirements and no resonance may occur for the axle housing caused by excitation of road.The automobile driving axle housing has sufficient rigidity,strength and shock resistance,providing an important reference for the design of future new product development and optimization.
