Based on 3D Virtual Prototype Technology and Finite Element Analysis of the Optimization of the Automobile Front Axle

Abstract

The front axle is an important part of a car, directly affects the dynamic characteristics of car. Based on UG NX6.0 for automobile front axle parts 3D modeling, finite element analysis software ANSYS modal analysis was carried out on the front axle, and extract their first four order natural frequency and vibration mode shapes, the automobile front axle structure stress analysis and stress distribution nephogram of get parts. Analysis of the impact load condition and emergency braking conditions modal analysis, and further to fatigue analysis of the front axle bridge shell, for provide valuable reference data for the reasonable design of parts. For the kinetics of further research and improvement of front axle provides the theoretical basis, but also provides reference to the actual test.
