Design and Development of Baja Roll Cage Based on Ergonomics

Ergonomics of a vehicle play a major role in ensuring drivers safety and comfort. In a case of an off-road vehicle where it overcomes a rough terrain and drenches the driver feels lots of vibrations and fatigue thus an Off-road vehicle demands a huge safety and ergonomic comfort. The chassis design for a Baja SAE vehicle requires a double focus on structural integrity and driver ergonomics to ensure safety and efficiency. This paper examines the ergonomic aspects important to the development of the Baja SAE roll-cage, with driver comfort, approach accessibility, visibility, control -That also includes emphasizing the importance of ease of use, and all are important for improving driver performance and reducing fatigue during driving. It also includes detailed analysis of anthropometric data to define the optimal shape and layout of the roll cages, with several major drivers complying with SAE safety standards. The CAD modelling and simulation software’s were used to analyze various design iterations and validation. The design focuses on improving access to the pedals and steering wheel, ensuring adequate head and legroom. Field tests were conducted with models to obtain useful feedback from the drivers, which implies iterative design improvements. The findings suggest that ergonomically optimized roll cages significantly improve driver comfort and productivity without compromising safety. The incorporation of ergonomic principles into roll-cage design gives Baja vehicle a competitive advantage through improved driver experience, which can improve race results and reduce injury risk. This study summarizes the need to adopt the balanced approach of the Baja SAE roll cage by integrating safety, performance with ergonomics into the design, it contributes to competitiveness and growth in the industry
