Side Impact Analysis of the Bus Frame Structure

Abstract

Vehicle bodies and structures should be designed to absorb and redistribute as much impact energy as possible, thus protecting the driver and passengers from injury. The deformation zone of the vehicle in the case of a side impact is smaller than in the case of a front impact. A side impact collision directly affects the structure of the vehicle. Composite materials may be used in the structure to reduce vehicle weight and improve vehicle deformation. Bodies and structures where composite materials are used have a higher SEA value. Using Ansys software package according to UN / ECE Regulation No. 95, a side impact simulation, when a deformable barrier moving at a speed of 50 km/h impact to a structure was performed. The simulation was performed with a steel and hybrid bus frame structure. The simulation results show that the deformation of the hybrid frame structure is close to the deformation of the steel frame structure and the SEA value is 12% higher.
