Abstract
Serious steering shimmy phenomenon has to be eliminated because it reduces the automotive performances and safety. Simulations and experiments are carried out on the issue of a light-duty truck. A diagnostic experiment-numerical simulations-improving experiment investigative process is applied to determine the main influence factors, which are the front suspense rigidity, the tie rod rigidity and backward inclination of spindle. The effect regulation is explored, and the measures to reduce the shimmy are proposed. Corresponding effectiveness of shimmy-reduction is validated in the simulations and experiments on a realistic vehicle that at the various running speeds the shimmy response acceleration of the floor of the vehicle-body is reduced by 25%-40%.
