One of the current trends in industrial wheeled vehicles is to increase their mobility, i.e. the ability to travel at speeds ranging from 50 even up to 100 km/h, e.g. military engineering machines. As a result of the high demands put on such vehicles several previously unknown problems with their dynamics have come to light. The paper presents the results of experimental and MSC Adams view simulation tests for snaking movement of an articulated frame steer vehicle such as bucket loader. The model precisely accounts for machine units’ mass and geometry along with their inertia. Additionally, the model includes hydrostatic steering gear submodel and its geometry and the submodel of a drive train with dynamic properties of multi-dimensional tyres as well. Experimental and virtual tests demonstrated that directional dynamics of articulated frame steer wheeled vehicles are largely affected by total (equivalent) steering gear torsional stiffness, dynamic properties of largesize tyres and type of vehicle’s wheel drive. Simulation studies used the results of experimental studies whereby the simulation outcome provides interesting and original guidelines for articulated frame steer vehicles manufacturers.
