Application of Taguchi Method to Simulation of Articulated Vehicle Steering Dynamics

A model of the steering dynamics of an articulated loader is used to study the steering system instabilities and sensitivity to various parameters in the steering priority valve. The Taguchi method is used to evaluate the combinations. The study utilizes an L12 array with six parameters varied on two levels. A verification simulation is run which results in a stable, well-damped system. This study demonstrates that the Taguchi method is a viable approach to solving hydraulic system instabilities.
