Purpose. The justification of the new equation of friction of flexible bodies, which confirm the concepts of friction of bodies during operation of transport machines with flexible tie body. Methods. A comparison of the known concepts of the friction of bodies, the influencing factors, and the solutions of the Euler problem of the sliding of a flexible body along a fixed block. Findings. The general factors of friction of inflexible bodies are established – frictional force and normal reaction between bodies, which are linearly connected, and a new equation of friction of flexible bodies is justified. Originality. For the first time it is established that the new equation of friction of flexible bodies: – includes the frictional force and the normal reaction between the bodies, which are linearly connected; – corresponds to the equilibrium conditions of the mechanical system; – coincides with the law of friction of bodies of Coulomb, which is common. Practical implications. New scientific knowledge widens the idea of the friction of bodies. They contribute to a deeper understanding of the physics of the process and the accuracy of conducting research, determine the development of technology and perfection of transport vehicles with a flexible body, increase their efficiency and operation safety.
