Research on Structural Analysis of Steering Based on Thermal-Structure

Abstract:

Stiffness and strength of the electric power steering structure were analyzed based on Catia, HyperMesh and ANSYS. Then, the influence of temperature on the stiffness of every component was also studied. The results indicate that the maximum deformations of the worm and worm wheel occur in the centre of the tooth top and their shape approximate ellipse. The deformation of the tail end of the worm-wheel shaft is large, and the limited groove area contracting the splined shaft and the steel ball bears large stress. The temperature load has some impact on the stress and deformation of components. The deformations of the components gradually enlarge with the increasing of the temperature, but the variations are not large. The stiffness and strength of steering can meet the design requirements.
