This thesis investigates the effect of geometric variations on the crashworthiness performance of new steering wheels. Experimental tests were carried out on steering wheel armatures from popular 1996--2001 compact vehicles. The armatures were subjected to impact loading using a drop tower testing device in which a 57 kg rigid plate impacted a steering wheel with a velocity of 3.2 m/s. The purpose of the experimental tests was to investigate the crashworthiness characteristics of steering wheel armatures from a similar vehicle line in terms of peak loads, Crush Force Efficiency, elastic response, energy efficiency, specific energy absorption and the Energy Absorption Factor. In order to obtain comparable results a rigid plate was used to impact the steering wheel armatures. Based on the findings, a parametric study investigating the effects of dish depth and 3 o'clock and 9 o'clock spoke angle was conducted. A safety rating system for steering wheel armatures was developed and the armatures were ranked in descending order.
