The Investigation of Design Parameters Influencing on On-Center Handling Using AUTOSIM

The chracteristics of a steering system, such as steering stiffness, power steering assisting force, gear ratio and friction, have been known as an influencing factor on the vehicle handling. Especially, the driver's feeling during straight running, so called on-maneuver feel, is of interest to investigate the steering effects on the handling qualities. This paper introduces a steering system modelling using the multi-body simulation program AUTOSIM.
