Abstract
Today car collisions are one of the transportation problems around the world
and on the other hand the real collision test is costly and time consuming. For this reason in recent years car collision simulation using various software has been used. In this dissertation, the side panel of Dena car is elementalized by HyperMesh software and then the collision of its finite element model is simulated using the requirements of ECE standards in LS DYNA software. In this regard, collision speed, vehicle connections, material definition, obstacle model and initial vehicle collision conditions are considered. Collision analysis is performed by a collision mode and standard requirements and structural optimization are examined. The collision is performed by the vehicle finite element model according to ECE R95 standard. The results show that by adding a composite pipe, the safety of the car in general collision is increased and more energy is absorbed (about 10%) and finally, due to the composite properties, the weight of the energy absorbing pipe is reduced by up to 80%. And as a result, the weight of the car is reduced and the fuel consumption of the car is reduced.
