According to the ministry of road transport in India, there are 1.5 million schools and around 260 million school-going children, and over half of them use school bus transportation facilities to travel from or to school. In short, school buses are one of the most important transport vehicles for school students, but according to the world health organization report, road accidents are the primary reason for death in the age group 5-29 years. India ranks at the top with the highest fatalities, with 11% of the total share in the world. There are many reasons for fatalities like speed, non-use of a safety system, and unsafe road infrastructure, but the fundamental reason is unsafe vehicle structure. According to school bus accident statics, frontal collision is the most hazardous in comparison with all other accidents because frontal structures get damaged easily, and this will lead to death and injury of the driver and crew member, which are the key persons in controlling the vehicle and ensure the safety of others. In this research work, we performed a pendulum test on the school bus superstructure as per AIS029 using LS-Dyna explicit solver.
