Abstract

Belt conveyors become more and more widespread in many industrial sectors of the Russian Federation and other countries. They vary by their design, performance, length, spatial configuration of the route, and other technical specifications. Current trends of increasing their performance, belt velocity, and length attest even more to the advantages of the conveyor transport. 40% of the cost of a belt conveyor of 240–480 m long goes to its belt, with longer conveyors having this indicator rise up to 75%. Increasing the service life of such an expensive element of a conveyor is obviously a pressing problem. Among the main factors which impact the service life of a belt are dynamic processes which accompany the operation of belt conveyors in both transitional and steady-state modes. The goal of the research is to study longitudinal vibrations in the conveyor belt using a modified method of Bubnov–Galerkin. The analysis of dynamic processes was carried out with the allowance for the dissipation of vibrational energy in its complex form. A minimal belt tension near the load tensioner was determined on the condition of excluding a loss of stability of the belt along the conveyor route.
