Design, Material Selection, Simulation and Manufacturing of ROPS and FOPS for Motor Grader 2023-28-1348
Motor grader is self-propelled, versatile machine widely used for road construction and maintenance in mining and construction applications. It required working in rugged terrain with uneven and slippery surfaces. Probability of rollover in motor grader is more due to the vehicle profile and high centre of gravity.
In light of the above, Roll over Protective Structure (ROPS) is essential to safe guard the operator from any fatal injuries / life during the operation of the equipment at different terrain conditions. Considering DGMS (Directorate of General Mines and safety) requirements, a rugged two post Rollover Protective Structure (ROPS) was designed as per ISO 3471 criteria for ROPS and Falling object Protection Structure (FOPS) as per ISO 3449
Material selection for ROPS and FOPS is one of significant factor in design process by meeting the design criteria. It should have dual characteristic, firstly, it is expected to tough enough to withstand sudden impact forces. Secondly, it should flexible enough to absorb the majority of energy during roll-over accident
A 3D model of the Roll over Protective Structure along with FOPS was created and the structure was analyzed using implicit finite element analysis (FEA) software to determine the force-displacement characteristic of Roll over Protective Structure.
Material performance requirement, Design and Simulation activities were studied. The Roll over Protective (ROPS) and FOPS Structure for Motor grader was manufactured and fitted on the equipment.
