Analysis on modal and structural strength of crive axle housing for micro-car

A simplified 3D geometry model of the drive axle housing is established with UG software,then it is imported to Hypermesh software and meshed by choosing appropriate element type,in which the meshed model is further imported to ANSYS software to provide a finite element model for following analysis.By applying ANSYS a static analysis under four typical conditions is carried out for axle housing,and the corresponding distribution of stress and deformation is obtained,which results show that the strength and stiffness of axle housing meet the requirements.In addition a modal analysis is done to get natural frequencies and vibration shapes under the first six modes of the housing,which results show that no resonance may occur for the axle housing caused by excitation of road,the design of the axle housing is rational.These results after the finite element analysis can provide some reference for improving design and structure optimizating in the future.
