“…In this study, Marc ver. 2020 (MSC software Corp., Newport Beach, CA, USA), which is widely used for the structural analysis of the tractor ROPS in Korea, was chosen [21]. This is a generalpurpose, commercial analysis software package that is compatible with various FE model files and has auto-remeshing and refinement functions useful for the analysis of the nonlinear behavior of the ROPS in load tests.…”

In this study, a model of the frame-type ROPS (rollover protective structure) for an agricultural tractor was developed using FEA (finite-element analysis). Various boundary conditions were applied as input variables to replace the actual test of the ROPS with a virtual test. An optimization study was carried out based on the boundary conditions of the bolt, considering the ROPS part directly mounted on the tractor and the folding connection to the ROPS. The results of the virtual test were compared with those of the actual test, and the error was determined. The maximum error of the evaluation model was 7.0% for the force applied on the load and 9.6% for the corresponding ROPS deformation. All mounting bolts of the ROPS required modeling. In particular, we had to establish free boundary conditions for axial rotation to implement the folding connection. In addition, a simulation of the frame-type ROPS was conducted according to the mesh size. A convenient simulation time was obtained for a mesh size of 8~10 mm. Compared with the actual test, the accuracy was the highest with a mesh size of 6~8 mm.

“…Tractor rollover test is a test to exam the stable angle and maximum stable inclination angle of tractor rollover. It is a necessary item for tractor supervision, inspection and popularization appraisal (Song H. S. et al, 2020). Passing the tractor rollover test is of great significance for controlling the height of the tractor's center of gravity, driving safely or operating safely in the field, which can not only improve the stability and safety of the tractor, but also reduce the incalculable accidents of the tractor during operation.…”

The tractor working environment is complex and changeable, and the dynamic variation range of the center of gravity position of the tractor body is large. In order to avoid rollover accident, an active anti rollover control method of tractor momentum flywheel and its model test are proposed in this paper. The tractor dynamic system model and control strategy are verified by a 1:16 scale tractor model. The research results show that when the model tractor crosses the trapezoidal obstacle B, the roll angle of the whole machine is temporarily stable near 35 °, indicating that at this time, the tires on one side of the whole machine are in actual contact with the obstacle, showing a short stable state of the whole machine. When the pavement roughness reaches F-H level, without any active anti rollover control, the evaluation index EP shows a divergence trend when it is greater than 1, and the simulation calculation is terminated due to the occurrence of rollover of the whole machine. The test data and simulation results under two different driving speeds are in good agreement, which verifies the effectiveness and reliability of the tractor rollover dynamic system model and the momentum flywheel active stabilization system.
