Drive axle housing is an important part in heavy truck. 3D model of the axle housing was made by software UG. The finite element model of automobile drive axle housing was built with simulation software NX.NASTRAN and the finite element modal analysis was achieved. 1-6 order natural vibration frequencies were got under three kinds of working condition which were the maximum traction force, the maximum vertical force and the maximum lateral force. The vibration frequency was far greater than the natural frequency in the actual work. The security of the drive axle housing has been validated.

In actual engineering, the drive axle of vehicles is often enlarged to prevent it from being damaged. However, the enlargement will increase the weight of the vehicle, pushing up fuel consumption and exhaust emissions. This common practice is obviously detrimental to the environment and sustainable development. To meet the stiffness and strength requirements on the drive axle housing of Steyr heavy trucks, this paper carries out finite-element analysis on the stiffness and strength of the axile housing under different working conditions, in the light of its actual stress features. According to the production process of drive axle housing in truck, the authors reviewed the development of the materials for high-strength axle housing, which could be properly formed through hot stamping, cold stamping, and mechanical expansion, and briefly introduced the structural features of drive axle housing. Then, a drive axle model was established in the three-dimensional (3D) drawing software Pro/ENGINEER, and converted into a finite-element model in Pro/Mechanica by calling the meshing command. On this basis, the static load of axle housing was analyzed under four working conditions: maximum vertical force, maximum traction, maximum braking force, and maximum lateral force. Finite-element analysis was performed on the meshed model to obtain the displacement and stress cloud maps of the axle housing under each working condition. The results show that the drive axle housing satisfy the requirements on strength, stiffness, and deformation. To sum up, this research improves the design efficiency and quality of products through finite-element analysis on the stiffness and strength of drive axle housing.

A finite element method (FEM) is used to make the modal analysis of the drive axle housing, the first ten natural frequencies and modal shapes are obtained. The parameter identification method is applied to obtain the experimental modes. There is a great agreement with the calculating modes and the experimental ones, which proves that the finite element method is rational. According to the theoretical analysis, the main deformations are bending and torsion at both ends of the drive axle housing and the deformation of the middle part is relatively high. The natural frequencies are at middle and high frequencies which are close to the mesh frequencies of the drive axle gears. Therefore increasing the thickness and redesigning of stiffened palates are applied to avoid the resonance region effectively.

In order to solve the heavy mass problem of the commercial vehicle drive axle housing, the structure of axle housing is optimized with finite element method. At first, the parametric finite element model of axle housing is built by using ANSYS software, and the dynamic response characteristics of axle housing are obtained with transient dynamics analysis. The dynamic analysis results show that strength and stiffness of axle housing can satisfy design criteria very well. Then the fatigue life of axle housing are predicted based on the dynamics analysis, and results show that the fatigue dangerous regions occur on the spring seats. Finally, the structure optimization of axle housing is done aimed at lightweight with goal drive optimization method, and the fatigue life of optimized axle housing are verified with FEA and bench test. The results of verification by both FEA and test show that the optimized axle housing has apparent lightweight effects with its fatigue life meeting design requirements.

The finite element model of drive axle housing was built by using the solid element and the shell element respectively. Vertical bend strength and stiffness under 2.5 times of fully load of the drive axle housing were calculated by finite element method. By comparing the results of the vertical bend strength and stiffness of both models, we could know that both of the two models can be used to analyze the whole stress situation of drive axle housing. Because there were fewer elements of drive axle housing model based on shell element, the amount of final calculation was less. It is more feasible to analyze the whole stress situation of drive axle housing by establishing drive axle housing based on shell element.

UG software was used to build the entity model for light truck driving axle housing, imported the model to ANSYS Workbench collaborative simulation software, and analyzed the stress after meshing and loading. It can be seen that the maximum equivalent stress of the drive axle housing under various conditions was less than the allowable stress value, and the evaluation index of vertical bending static strength experiment is Kn> 6, meeting the strength requirement; In the condition of full loads, the maximum deformation of the per-meter center distance is: 0.1 mm/m < 1.5 mm/m, also meeting the rigidity requirement; The experimental study is used to verify the analysis results referring the relative articles, shows that analysis results are reliable. This process provides reference for other driving axle housing and similar structure finite element analysis.
