Abstract

The intermediate shaft assembly of a vehicle steering system is an intermediate member that transmits steering torque tothe gearbox. It is a critical member that affects the collision absorption, safety, and other vibration/noise absorption. In thisstudy, a finite-element analysis model is developed to evaluate the torsional stiffness performance of anintermediate shaft assembly for vehicle steering. All components are omitted except for the main components thataffect torsional stiffness. Contact conditions are applied between the components, including the yokes, shafts,needles, and spiders. The torsional stiffness calculated via finite element analysis is compared with experimentalresults. The finite-element model presented in this study can predict the torsional stiffness of an intermediateshaft assembly. Furthermore, it can be used to reduce the cost and time required for the design and fabricationof experimental prototypes. In the future, we will develop a finite element model that can predict variousperformance parameters, such as strength and fatigue.
