A comparative analysis of the structural and technological features of the assembly of multi-deck and single-desk vessels of presented, indicating the distribution of the volume of saturation of the latter with pipe elements, systems and mechanisms. On the basis of the principles of zonal aggregation, a solution to the zonal module of the engine room of small vessels is proposed. In order to eliminate the diffi culties of assembling the hulls if single-deck small vessels and mounting saturation in them a new scheme for dividing these hulls into two volumetric asymmetric parts with the allocation of the engine room module, extremities, deckhouse and burl is considered. The calculated data on the reduction of labor intensity and duration of the assembly of hulls of single-desk small vessels in the implementation of their division according to the new scheme are given.

The influence of disturbing forces in a system of frictional self-oscillations with a Van der Pol characteristic is investigated. In the differential equations of the research methodology, three types of external forces periodic disturbances are taken into account: harmonic, impulsive and shock, as well as the presence of various types of complex nonlinearities elastic, dissipative, or simultaneously elastic and dissipative. To reduce the amplitude of oscillations, sometimes reaching significant values, force action is introduced into the system. Its structure and parameters are determined based on the methods of the theory of harmonic linearization and optimal control.

The dependences of the spacer force and feedback gain on the current value of the friction coeffi cient are found, for which an adaptive friction coupling with a variable gain value has a theoretically ideal load characteristic. It is proved that the real way to increase the coeffi cient of multiplicity of increasing the rated load capacity of the coupling is to increase the number of friction pairs of the friction group.

The paper describes ways to increase the bearing capacity of sliding bearings. The possibility of replacing a rolling bearing with a sliding bearing on a high-speed worm gear shaft is shown. A description of the dynamics of self-oscillations occurring in the worm gear is given, followed by an assessment of the effect of fi lm-forming lubricants on the adaptive properties of sliding pairings. The resource of sliding pairings is calculated taking into account the growth of the dinamic coefficient.
