Annotation	The problems of longitudinal – transverse vibrations of objects with moving boundaries were solved mainly in a linear setting, the energy exchange through the moving boundary and the interaction between longitudinal and transverse vibrations were not taken into account until now. The paper presents a new nonlinear mathematical model of transverse vibrations of an unbounded rope with a moving boundary, in which geometric nonlinearity is taken into account. The obtained mathematical model allows one to describe high-intensity vibrations of a rope with a moving boundary. The solution was made in the MATLAB environment of dimensionless variables, which allows one to use the obtained results to calculate oscillations of a wide range of technical objects.
Keywords	nonlinear mathematical model, vibrations of a rope, moving boundaries.
