Logistics and passenger transport remains the dominant motive for the utilization of vehicles in Indonesia. In the 5 years span of 2015 to 2019, vehicle growth in the country has significantly increased with an average value of 7,000,000 annually, in which trucks and passenger cars contributed to over 4% and 5% each. As the result, accident occurrence has also escalated along with it, where truck and passenger cars are involved in an accident over 20,000 and 17,000 each year on average. Among them, 16% of the point of impact occurs on the rear of the truck against the front of a car, with 94% serious to fatal injury resulting from a Passenger Compartment Intrusion (PCI). Rear Underride Protection Device (RUPD) is a device installed on the rear end of the truck to reduce or even preventing up to 63% of fatal injuries on high-velocity vehicle cases. In this thesis a parametric study for quasi-static testing will be conducted on the device to determine the impact and significance of support structure angle along with structure thickness on deformation and maximum equivalent stress, utilizing finite element method aided by ANSYS LS-DYNA software. United Nations Economic Commission for Europe (UN-ECE) has standardized the design and testing requirements for RUPD under Regulation 58 (R-58), which will be used as a reference on testing conditions for this study. Simulation result shows the decrease of support structure angle decreases maximum deformation and stress in the RUPD, with the optimum angle of 20°. The increase in thickness structure thickness will also decreases maximum deformation and stress. It is hoped that the parameter studied could be used as a way to further develop and optimize existing models of RUPD especially in Indonesia.
