ROPS is a structure installed to protect drivers from tractor rollover accidents and is being tested for certification under the OECD code. Because this test requires a lot of cost and time to develop the ROPS and to produce test model, the OECD is discussing the introduction of virtual test using finite element analysis. In this study, the results were compared by conducting a strength test and finite element analysis applied with the OECD code to use it as a basic data for standardization of ROPS virtual test methods. It was confirmed that the results of the analysis of the bolts and plates of the coupling part and the folding part were more close to the physical test results than the rigid elements and constraints at the point of coupling the tractor and ROPS.
