The World Health Organization reports that road traffic accidents remain a global epidemic, tragically claiming 1.35 million lives yearly. One significant contributor to this alarming statistic is collisions involving cars and heavy trucks. Innovative safety measures, such as Rear Underrun Protection Devices (RUPDs), must be developed and implemented to address this issue. This study evaluated a new RUPD design based on the Indian Automotive Standard of RUPD regulations. This study used 3D-CAD modelling and Finite Element Analysis (FEA) to create a robust RUPD design that could withstand collision forces. Through FEA simulations, we discovered that the RUPD had excellent energy absorption capabilities and reduced deformation during impacts. The 3D-CAD design of this new RUPD emphasises the crucial role RUPDs play in enhancing road safety. SolidWorks CAD modelling and FEM analysis techniques using SolidWorks Simulation & Ansys Software are potent tools for optimising RUPD performance & strength parameters based on deformation for given loading and boundary conditions, setting a benchmark for future research and development efforts in road safety.
