A comparison of locating charts with passive adaptation and hard basing for robotic assembly of cylindrical parts of the "shaft—bushing" type is presented. The results of a physical experiment and an analytical solution to the problem using the original models of the robotic assembly in a quasistatic setting are compared. The reactions at the contact points that occur during the coupling process are determined.

Technological processes of assembly of the most mass metal-ceramic IC cases with planar and pin contact conclusions on the automatic modular line are considered. It is proposed for the automated shop of assembly of cases to combine the assembly line and a site of automatic cassetting it into a single transport-accumulative system. The introduction of the IC hull assembly line into production provides an increase in labor productivity by 3...5 times while reducing the number of service personnel by an average of 3 times.

Dimension chains were calculated using the example of a jet engine housing entering the launch tube. It was found that the method used does not take into account the actual values of losses and requires signifi cant reliability in the radical runout of the collected rocket engine case. A method for controlling radial runout in prisms is also considered.

Theoretical model has been developed for predicting the average stress values during melting of water frozen in silicon-based mesoporous structures in the temperature range 233...273 K, caused by the difference in the thermal expansion coeffi cients of the heterogeneity elements in the materials studied. Numerical calculations were carried out using and dependences of the average stress tensor components on the volumetric water content in the mesoporous silicon matrix were investigated.

The methodology for determining the minimum allowable feed per tooth and maximum possible tooth lift is presented. Given the fact that with a decrease in the thickness of the metal layer being cut, the specifi c cutting force increases, in order to reduce the pulling force when designing broaches, it is necessary to strive to choose the maximum possible tooth lift.

The formation of boundary lubricating films on the surface of steel during friction in the presence of substances forming complex compounds with iron — dipyridyl, o-phenanthroline, 8-hydroxyquinoline, and ethylenediaminetetraacetic acid, is considered. Boundary layers formed in the presence of complexones increase the antifriction properties of the lubricant at low loads. It has been established that surface films are formed predominantly from base oil molecules.
