Experimental Studies on Bending Cardboard by Pushing It Through a Matrix

A research stand has been developed to conduct research on the phenomena that accompany the bending of cardboard / paper during the manufacture of the bottom part of food containers and containers. A universal experimental stand for studying the pro­ perties of corrugated cardboard has been adapted to another material – folding card­ board; a program of experimental research has been developed aimed at determining the linear specific load when bending a flat material by 90 degrees perpendicularly and across paper fibers.

Theoretical foundations for the development of experimental equipment for determining the load capacity of speed change devices

The article gives the theoretical base for construction of equipment for experimental research of static, kinematic and dynamic characteristics of devices for speed change by epicyclic gear trains with closed circuit hydrosystems through the ring gear during the transmission by them of the periodic, shock long-term or short-term loads or their executive mechanism stoppage due to overload.
