Abstract—The main purpose of this study is to investigate the behaviour of four post Roll Over Protective Structure (ROPS) for agricultural wheeled tractor. The objectives are to assess the stresses and deflections in the ROPS of different cross-sections under different types of load conditions and compare the results to find out the most suitable type of cross-section. The ROPS is modelled by SolidWorks 2013 and analysed using ANSYS 14.0. Alloy steel is used as ROPS material. Three types of loadings are being investigated: rear loading, side loading, and vertical loading. Four types of cross-sections are being examined: square, circular, hollow square and hollow circular. This particular test is carried with accordance to SAE J2194 standard. This paper will present the stresses and deflections experienced by the ROPS.
