OPTIMIZATION OF CAR DOOR HANDLE USING HONEYCOMB STRUCTURE AND 3D PRINTING TECHNOLOGY

Abstract

Car doors are the crucial hardware used by humanbeings in day to day life. Doors of the vehicles are used for security purposes. To use the door in the efficient way, we need handle and it is the most important part in door. Door handles are used for opening and closing of a door with less effort. Various types of door handles such as lever handle, doorknob are the different kind of handles we came across in our daily life. There are various designs of door handles are already available so that we are not aware of door handles selection criteria. The aim of this work is to study the different materials and internal design of car door handle. For that purpose we used Finite Element Analysis (FEA) software to know which material and shape have more strength and optimize design. In this project we used two different structure one is honeycomb structure and other is auxetic structure for inside section of car door handle. Optimized car door interior handle will be manufacture using 3D printing technology. The behaviour of this structures under three point bending were investigated by using UTM
