Buckling of the multistage hydraulic cylinders

Constructions and Design Engineering

In the paper, the emphasis is placed on the elastic buckling of the system of multistage telescopic hydraulic cylinders under the assumption of well-formed contacts between the individual cylinder stages. In the paper, the recent relevant scientific publications in the field of buckling of THCs are presented and the corresponding solutions are introduced. Starting from the differential equation of buckling of the ideal uniaxial compression element with constant cross section and its basic solution derived by Euler [2], a corresponding theory of buckling is presented. Based on the chosen analytical methods, the critical buckling force of the real test THC is determined. As part of the study, a test rig is constructed and the measurements of buckling force are performed. Finally, the comparison between the measured and calculated results is shown.

Host city and venue - Belgrade

Belgrade is the capital and largest city of Serbia and a city of very tumultuous history. Belgrade was the capital of Yugoslavia from 1918 to 1991. It is located at the confluence of the Sava and Danube rivers, where the Pannonian Plain meets the Balkans. It is one of the oldest cities in Europe and since ancient times it has been an important traffic focal point, an intersection of the roads of Eastern and Western Europe. Read more...
