| Abstract |
In mining and metallurgy, multi-purpose self-propelled vehicles are widely used as in-house and workshop vehicles. This paper presents the results of a study devoted to the substantiation of the structural and technological parameters of the steel frame structure of a multi-purpose self-propelled vehicle (in-house vehicle) with a lifting capacity of up to 2 tons. The main causes of the frame defect, as well as design errors in its design, are analyzed. The importance of obtaining rational characteristics of frame strength and rigidity with minimal weight, as well as adaptability in manufacturing and repair is emphasized. The design features of the spar steel frame structures, the requirements for the materials of the bearing systems, as well as the characteristics of the steels used in their manufacture are considered. As a result of the studies of the bearing system of the in-house vehicle, maximum load zones, potential destruction sites and areas requiring additional reinforcement were identified. Based on these data, computational experiments have been conducted on various reinforcement options for critical frame elements and studies of the possibilities of using other types of steels. For the existing frame structure of an in-house vehicle, two variants of the structural and technological parameters of a steel spar frame structure were substantiated by computational experiment. The first option is recommended for use in the manufacture of the frame, and the second for its modernization in the already manufactured design of a self-propelled vehicle in order to eliminate the shortcomings identified during the operation of the vehicle (in case of a complaint). The effectiveness of the proposed design and technological solutions was confirmed by their introduction into production and subsequent operational experience of the considered vehicles. |
