| ABSTRACT |
|
This paper is focused on analyzing the stress and strength of a heavy truck drive axle housing. The analysis is conducted using mechanical principles, and four typical working conditions are taken into consideration. A three-dimensional model of the drive axle housing is created with Solidworks and analyzed with ANSYS to establish a finite element model. Static analysis is carried out on the four typical working conditions, and the corresponding stress and deformation values are obtained. The maximum stress and deformation values obtained are 388.66 MPa and 0.901 mm, respectively, and both of them meet the required standards. Based on the results from static analysis, a stress-life curve for the material is created. Subsequently, fatigue life analysis is conducted under full load conditions using finite element methods. Finally, the design of the axle housing is verified for its reliability. |
