One of the last trends concerning articulated rigid frame vehicles is to increase velocity of their movement beyond 50-60 km/h. Significant differences in construction chassis system this kind of vehicles to distinguish automotive vehicles, makes that it is difficult to follow stragight path course by operator. It is caused for example by a very low equivalent stiffnes of hydraulic steering system, the contact method of large size wheels and others. While constructing articulated rigid frame vehicles a very few parameters could be changed. Both numerical and experimental examination shows a crucial influence of stiffnes steering system on trajectory of this kind vehicles. In this article a various methods of construction steering system are examined to improve their stiffnes. The value of equivalent stiffnes of actuators steering system is measured on a real articulated vehicle. The simulations are made in MSC ADAMS environment. The present paper will include an analysis of the impact of the steering system geometry on the achieved motion trajectory. The virtual and physical model of the investigated articulated industrial vehicle researches are put as well as the comparison between considered variants of the steering system.
