Abstract: BACKGROUND: The motion of transport and technological vehicles (TTV) with increased and high cross-country ability, as well as all-terrain vehicles, must be efficient. This paper examines the method for studying the efficiency of TTVs based on the mobility criterion. AIM: Evaluate the efficiency of wheeled TTV using the mobility map building method. METHODS: The method for determining the efficiency by mobility as the most informative indicator covering the largest number of configuration characteristics of a TTV is used. Based on the calculation of the efficiency indicator by mobility, mobility maps that reflect the predicted efficiency (speed) of the TTV movement in the basic and modified versions were built. The object of the experimental studies was the “Baikal M” ZTM 30081-11 wheeled all-terrain vehicle. The full method is described in paper. RESULTS: As a result of changing the configuration characteristics based on the results of theoretical calculations and experimental studies, the applicability of the method was confirmed and the efficiency of the Baikal TTV was improved. The mobility indicator was increased by 4.7%, and mobility efficiency was increased by 3%. The experiment confirmed increase of obstacles passage velocity. CONCLUSION: As a result of the study, the method for studying the efficiency, which is applicable both at the design stage and at the stage of upgrading a TTV configuration, was approved. By changing the calculated characteristics, it is possible to determine the reasonable configuration of a TTV without costs on the production of prototypes.
