Calculations of vibrations of individual modules of a towed system near their equilibrium positions

Normal operating conditions of towed systems are determined by the impact of factors that vary over the operating time of the complex. Providing only the physical and mechanical properties of the towed system modules does not generally guarantee successful operation of the complex. This paper considers the development of towed systems and the oscillations associated with their operation during towing. Based on known provisions of theoretical mechanics, oscillation theory and hydromechanics, equations are constructed that describe the oscillations of towed systems. The example shows that the solution of the proposed equations allows one to select the module that experiences the greatest impact from the pitching of the towing vessel and/or horizontal speed of movement in dynamics. The obtained solutions can become the basis for making design changes to the towed system. A method for determining the speed of the ship's winch when immersing the towed system is also proposed. The example shows a rational choice of the speed and time of immersion of the towed system. The results of the conducted research can be useful for developers of towed systems.
