Statistical analysis of load spectrum is an important part on structural fatigue life and reliability research, it is generally considered that axle’s load spectrum follows Weibull distribution. This paper tested ZL50 loader’s loading history of different working conditions , and obtained the corresponding load spectrum by rain-flow counting method, then analyzed three distributions’ (normal distribution, lognormal distribution, Weibull distribution) fitting degree of load spectrum and effect on the fatigue reliability. Results show that the highest fitting degree of distribution function should be used to fit load spectrum, which can reduce the error in structural fatigue reliability prediction.

In order to estimate the residual life of waste drive axle housing, the prediction model of waste axle housings with artificial neural networks is built in this paper. Take the deformation, residual stress and the gradient of magnetic intensity Kmax relating to axle housing’s fatigue damage degree as the input of neural network, and compare the testing residual life of the waste drive axle housing with its predicting residual life. The result demonstrates that: the deformation, residual stress and the gradient of magnetic intensity Kmax of axle housing as the characteristic parameter estimating the degree of fatigue damage, adopting trainbr training function can get good network performance and comparatively high precision of prediction. Besides, the longer the residual life of the waste axle housing is, the more precise the prediction life will be.

Drive axle housing is one of the major load-supporting components of trucks. This paper takes a drive axle housing of a light commercial vehicle as the research object. The model of the drive axle housing is established by Pro/E software, on the basis of this model, the finite element analysis is carried by ANSYS to get the results of stress and strain under the defined constraints and loads, to find the weak links in the design. Aiming at achieving the goal of the least weight, the permission stress and displacement are defined and the thickness of the drive axle housing is considered as the design variable to optimize the design. The result of optimization design provides a theoretical guidance for truck driving axle housing designing.

Element Method

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.

Drive Axle Housing

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.
