Abstract

Using the techniques of structural analysis based on traditional and modified kinematic graphs comparative analysis of the structures of the two real structures of passive relaxation shock absorbers. It is shown that the modified kinematic graph efficient for analyzing structures requiring mechanisms accounting for elastic, dissipative or other links between elements of the structure, the change of which is directly related to the kinematics of the mechanism under consideration. Suggested by the use of modified kinematic graphs for the synthesis of structures dissipative mechanisms with enhanced functionality.

Abstract The article is devoted to theoretical and experimental study of the formation of holes on the surface to be treated by a single electric-contact exposure. Using a mathematical model of the formation of impact craters to derive an equation enables us to calculate the trajectory of the maximum emission of liquid metal from the hole because of its thermal characteristics and energy of a single electrical discharge. The results of his numerical studies reflecting the impact energy of the electric discharge and the conditions of its occurrence on the geometric parameters obtained on steel and titanium surface wells. The description of the methodology for conducting experimental studies, the results of which confirmed the accuracy of the mathematical model of the process of formation of holes on the metal surface after a single electrocontact exposure.
