Design sustainability of rollover protective structure in tractors

Abstract

Rollover Protective Structure (ROPS) design is becoming more important in tractors. Static analysis in accordance with the SAE J2194 standard is necessary for the designing ROPS prototypes that maximize safety while minimizing environmental impact. Using renewable and recyclable materials, energy-efficient production techniques, and sound design concepts to increase lifetime and durability are important tactics. In order to promote cradle-to-cradle design principles, the lifecycle assessment approach is utilized to examine environmental implications from material extraction to end-of-life disposal. The study shows how sustainable ROPS can be achieved by maximizing material consumption, putting modular designs into practice, and making sure that regulations are followed. To promote economic and social sustainability, factors like worker safety, local production, and recyclability are also taken into account. This analysis is a framework for designing ROPS that not only ensure operator safety but also contribute to broader sustainability goals, supporting a more sustainable agricultural sector. In this study, static load analysis on ROPS frame with different cross sections and loading conditions was performed using Finite Element Analysis (FEA). Three different cross sections were investigated: square, circular, and hollow circular. The produced stress, strain, and deformations under combined loading circumstances can be used to assess ROPS performance. The post-processing results reveal that the material qualities, shape, and loading conditions have a direct impact on the static load behaviour of ROPS. In comparison to other cross sections, the circular cross section has a high load bearing capacity and minimum deformation.
