Abstract: By introducing the influence of uncertain factors on the mechanical properties of drive axle housing, this paper investigates the method improving the reliability of the optimisation scheme of a drive axle housing of off-road vehicle. Firstly, the finite element model of the drive axle housing is established, and its simulation is carried out according to the bench test standard. Then the Monte Carlo method is applied to study the influence of uncertain factors on the reliability of the axle housing. And the lightweight design of the axle housing is performed based on the 6σ theory. The result shows that the weight of the axle housing is reduced by 12.48% under the premise of every performance with high reliability.

Keywords: drive axle housing; finite element analysis; Monte-Carlo method; reliability; lightweight design.
