Design of an adjustable prop made of Polymeric material

Abstract

In this work, an adjustable prop made of polymeric material was designed. To do this, standards that refer to this element were consulted and which specify that the load that the prop must support is 6000 N including live loads and dead loads. Consequently, the selection of the appropriate polymer for this application was carried out through a comparison of the mechanical properties of these materials, with acetal proving to be better. With this information, a buckling analysis was carried out using the analytical method considering an adjustable prop length of 3 m. In addition, supported by the Solidworks® software, a simulation of the critical load and contact stress was also carried out, resulting in the fixed part of the adjustable prop being a tube with an internal diameter of 80 mm and an external diameter of 95 mm. The adjustable part must be solid with a diameter of 80 mm
