Design and analysis of tractor roll over protective structure for the influence of deformation, stress distribution and strain energy

Abstract

Roll over protective structure is an important safety device used to ensure that the tractor operator is free from injury when an accident happen. In case of tractor moving in an inclined plane (or) overturning, may be the tractor met with an accident due to roll over (or) fall over of the tractor. Sometimes, tractor may unbalance due to change the position of Centre of Gravity. Designer is to provide safe environment for the tractor operator during an accident. So that roll over protective structure is to save the life of tractor operator and protect from death. Therefore, ROPS design in the tractor by model, static and dynamic analysis as per the ISO 3471:2008 standard before prototype development. The main objective of this paper is to determine the ROPS stress distribution and deformation accurately under different load conditions by finite element method.
