Finit element Analysis and Optimum Design of Time-sharing 4WD Vehicle Main Reducer

摘要

By carrying on the stress and transform analysis of the box of a kind of main reducer which was self- designed and manufactured for vehicles, by ROMAX modeling get accurate bearing load and conducting ANSYS finite element analysis. it is shown that structure design of the main reducer box is very important for the intension capability of the box, and for the transmission functions of the main reducer. The hidden trouble of the main reducer transmission due to the designers was solved, which couldn't estimate the transform of main reducer box by traditional design method, and provided the necessary basis for further optimizing and ameliorating the whole transfer case system. By using the UG software we constructed a complicated model of the box, and carried on a series of accurate intension and fatigued analyses for the model by using ANSYS software.
