Abstract: The article defines a rational type of front suspension for promising developments in the field of dump trucks with payload capacity from 200 to 240 tons. The current developments in the field of front suspension design are evaluated based on the results of analogues review. Analysis of all suspension designs, applied on the actual models of dump trucks by the leading world manufacturers has been made. Quantitative quality indicators of the considered suspension designs have been established with subsequent rating assessment of each design. The method of multi-criteria analysis has been applied to analyze suspension types by performance characteristics. As a result of the multicriteria analysis, three most promising suspension designs were selected for further elaboration. Computer models were made for these designs in order to estimate the range of variation of kinematic parameters of the suspension and to evaluate the rationality of the layout and manufacturability of the suspension units. The results of the analysis show that the independent front suspension of McPherson type on the longitudinal lever for dump truck with carrying capacity from 200 to 240 tons most fully meets the requirements.

Key words: suspension evaluation of the manufacturability of suspensions operational characteristics of suspensions analysis of the suspension design dump truck
