Sergey K. Rationale of rational design of the truck crane telescopic boom

The author solved scientific problem of reliability and stability of the truck crane telescopic boom by establishing rational design based on its section minimize the stress arising from the action of external loads. The analysis and evaluation of existing structures telescopic arrows, methods of modeling and calculation. Identified parameters and characteristics that influence the choice of cross-section section boom. Grounded mathematical model of interaction used arrows and theoretical studies performed to determine the stress arrows in the elements of possible vibrations, flexures and limits of stability arrows. Identified patterns of these parameters depending on the external loads. Experimental investigations established numerical values of the unknown parameters, the influence of geometrical and force characteristics of the choice section telescopic boom. Formulated and founded the most efficient design section arrows.
