Finite-Element Analysis on Lightweight Material of 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.

Design of Steering Driven Axle for QAY125 Ton Automobile Crane

Driving axle loader is a key component for loader. For the steering drive axle of the QAY125 all terrain crane, the main parameters of the main reduction gears and drive axle housing have been designed and calculated. By adopting the method of optimum matching between engine and transmission system parameters, the ratio of the main reducer is determined by the optimum design. Considering the drive axle housing structure and the force is very complex, in order to ensure the strength of full static strength check calculation of impact load and emergency braking of the three cases, calculations show that the axle strength design can meet the design requirements. The half shaft diameter is calculated by using the maximum torque, when the half shaft diameter is 45mm, the material selection 42CrMo, the half shaft safety factor is 2.09, completely meet the use requirements.

Finite Element Analysis of Automobile Drive Axle Housing Based on ANSYS

The performance of automobile drive axle housing structure affects whether the automobile design is successful or not. In this paper, the author built the FEA model of a automobile drive axle housing with shell elements by ANSYS. In order to building the optimization model of the automobile drive axle housing, the author studied the static and dynamic performance of it’s structure based on the model.

Finite Element Modal Analysis on the Drive Axle Housing of Heavy Truck

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.
