Stability of a hydraulic telescopic cylinder subjected to generalised load by a force directed towards the positive pole

Abstract

The paper presents the boundary problem of the stability of a telescopic hydraulic cylinder subjected to a generalized load with a force directed to the positive pole. The boundary problem was formulated on the basis of the Hamilton principle. Numerical calculations were carried out, taking into account the influence of the parameters of the load heads (radii of loading and receiving head, length of bolt). On the basis of the numerical calculations, regions of load heads parameters were presented, at which the load bearing capacity of the analysed telescopic hydraulic cylinder is the largest from the buckling standpoint.

A review on the employment of the hydraulic cylinder for lifting purposes

“…Uzny and Kutrowski [50] tried to identify numerical simulations of the critical load of the telescopic hydraulic system based on load head characteristics. They spoke about the stability problem of a hydraulic telescopic cylinder exposed to a public load with a force directed towards the positive pole.…”
