Torsional stiffness of steering column: finite element analysis and parametric study of steering column
2000 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

This report describes the FE analysis and factorial design study of a steering column designed for a new generation of Volvo cars. The analysis is carried out with respect to the torsional stiffness. High torsional stiffness is desirable to achieve good handling characteristics. The purpose of this work is to determine what parameters have the greatest affect on the torsional stiffness. It is also desirable to improve the model and compare it to the original model. The software I-DEAS Master Series 7 is used for the FE analysis and the method of factorial design is used for the parametric study. Five parameters are studied: The play in the bearings, rotational stiffness of rubber coupling, bending stiffness of rubber coupling, Y-translational stiffness of the bolt in the B-point and X-translational stiffness of the same bolt. The two most significant were found to be: 1. The rotational stiffness of the rubber coupling 2. The play in the bearings in the U-joints
