Finite Element Analysis of Rollover Protective System on a Three-wheeler’s Chassis

Sudeep Nair, Ankitkumar Dandiwala, Debashish Chakravarty and Basab Chakraborty


Rollover Protective System (ROPS) is one of the key components that is included in the chassis framework for the safety of the driver. The density and the Young’s modulus of the material of ROPS need to be carefully considered for performing Finite Element Analysis (FEA) to minimize deformation and stress concentration near joints. The deformation, von Mises stress and strain contours are obtained for ROPS under static structural loading conditions simulating the dynamics of vehicular rollover and toppling in ANSYS. It was observed that the maximum deformation was obtained on the part of ROPS that came into contact with ground headfirst. Changes were made in the weldment material assignment till the deformation was reduced to permissible levels for both the cases, i.e., toppling and rollover. The modified deformation contour for toppling force produced a 64.5002% decrease in the deformation from 13.237 m to 4.6991 m. The modification in the material of the ROPS, specifically the use of default structural steel for reproducing the rollover force, has brought about a 64.5005% decrease in the deformation due to the rollover force from 12.163 m to 4.3178 m.
