DESIGN AND IMPACT ANALYSIS OF REDUCTION OF WEIGHT IN CAR DOOR

Abstract

Car door is one of the main parts which are used as protection for passengers from slide collisions. Doors
are typically hinged but sometimes attached by other mechanisms such as tracks, in front of an opening which is used
for entering and exiting a vehicle. Side impact collision of vehicle is one of the awfully hazardous crashes causing
injuries and death annually around the word. In this PROJECT, the most important parameters including material,
geometry and rib arrangement were studied to improve the crashworthiness during vehicle-to-vehicle side collision. In
the side impact, the side door impact structure is responsible to absorb the most possible kinetic energy. Presently steel
is used for car doors construction. We designed side impact beam of different cross sections. The design of car door is
designed using CATIA. The aim of the project is to analyze the car door with presently used material steel and
replacing with composite materials like aluminum, carbon epoxy, s-glass epoxy, e-glass epoxy. Impact analysis is
conducted on door with transient structural analysis using ANSYS software by varying the materials.
