The efficient functioning of an assembly line is largely related to two tasks — the selection of equipment for the assembly line and the distribution of work between the workstations as well as the workstation and the person. A review of scientific research aimed at solving these problems is given. An invariant approach to the types of technological operations is proposed to automate production, which allows to solve successfully, including the designated tasks.

The method of actively changing the state of self-oscillations in machines and mechanisms in a system with various types of nonlinearities of an arbitrary structure under the action of external periodic perturbations was proposed. The differential equations of the method take into account two types of external force periodic disturbances: impulse and harmonic.

The results of the application of an inorganic polymer of zinc phosphorovolframate as an antifriction and anti-wear additive introduced into vaseline and glycerine, used as a dispersion medium for created lubricants are presented. It was found that the introduction of this type of additive into such dispersion media improves the tribological properties of lubricants without reducing the operational parameters.

The mechanical and tribological properties of thermoplastic polyimide based composites loaded with polytetrafl uoroethylene and milled carbon fibers, annealed and functionalized with a KH550 silane-coupling agent were studied. It has been revealed that, compared with neat PI, the composite with annealed carbon fibers and PTFE particles possessed the highest wear resistance. Reinforcing carbon fibers of hundreds micron size increase the elastic modulus by 2 times; while all other physical and mechanical properties remain at the level of unfilled PI.

Trobological characteristics of sliding friction in stainless steel and titanium alloys in dry and water lubricated conditions have been determined. The character of the coefficient of friction variation with load and the duration of tests have confi rmed the prevailing wear mechanism in these materials to be frictional fatigue fracture that in the case of titanium alloys is accompanied with adhesive interaction and plastic plowing. The frictional fatigue curves built in a result of this investigation make possible to estimate the materials tribological longevity.
