In this paper, the experiences and features for designing Dongfeng Special Axle Housing Factory who has an annual output of fifty thousands rear axle housing assemblies and gearbox - case assemblies of Dongfeng truck are introduced.

Finite Element Analysis on the Rear Axle Housing of Vehicle;

Producing Motor Rear Axle Housing with as cast Ferrite Nodular Iron Which is Melted in Cupola Furnace;

Elephant skin defect is easy occur on ductile iron rear axle housing castings.

Technological Analysis on the Car Rear Axle and Its Solutions;

By establishing a finite elements mechanics calculation model of rear axle,confirmed the edge conditions,all joints and stress for seven kinds of work conditions about two kinds of finite elements models were analyzed and compared,as well as the rear axle s original model and dabber model.

Techniqu from the probabilistic perturbation method and constraint random direction method are employed to present a practical and effective method for the reliability optimization design for the back-axle housing of vehicles on the condition of known probabilistic characteristics of original random variables.
