Light Weight Material for Automobile Essay

world-wide segment railway car with sapless pitch alloys and metal matrix composites 1. 1 Analysis An carmobile is a single biggest polluter, as sacks from millions of vehicles add up. As motor vehicles have been huge sources of pollution for the world since the last snow years, the major car companies and marketplace see profit by introducing well-nigh new technologies to overturn emission and delivering best solutions to customers. One of the major reasons for emission is weight of the vehicle. As weight increases degree centigrade emission increases and fuel capability decreases.Both equally reduce customer perceptions. Present market battles to reduce carbon emissions and to fulfill customer demands for highly fuel efficient vehicles. As the above statement is top priority in present market and glide path future, metallic parts of a general segment car allow be replaced by gentle weight alloys by coming decades. However significant terms challenges are there for u sing light weight physicals from manufacturing process to end life cycle. Smartly tackling of this cost will be the key to market applications.1. 2Strategic sense which helps to make light weight unit vehicles Global warming, global fuel prices and fuel demands are going to a critical situation, which makes human to think alternatively. As much fuel uses, more CO2 produces. If majority of vehicles made by steels are replaced by jackanapes vehicles, it will reduce the global fuel needs. As this initiative makes really good advantages to world, it will get a lot of co-operation from other industries governments and policy-making systems.Technologically and economically there are a lot of challenges and things to be done. Much R&D works to do. Right from material selection, ingathering design, process design, manufacturing methods, joining methods all has to be redesign for established organizations. It is a very big challenge. 1. 3 Initiatives taken to make light weight down v ehicles To achieve a light weight bodily structures, without compromising rigidity auto engineers have been researching the replacement of steel with plastics, aluminum and magnesium.Using of advanced material for reducing weight is the least expensive way to reduce zippo consumption and carbon emissions. It is found that * For every 10% weight simplification in weight of a car will result in 5% -7% improvements in fuel efficiency. * For every kilogram of weight diminution of a car will result in the reduction of carbon dioxide about 20kg. 1 1. 4 Weight saving and relative cost for light weight material Figure 1. 1 Relative material properties and cost 2.Important key factors while using advanced light weight materials are manufacturability, cost and joining processes. But as requirement is the overprotect of invention, manufacturability of aluminum and its composites will become easier and economical by coming years. Different manufacturing techniques are there to form aluminu m into want shape. 1. 5 Vehicle Case Study Super light railway car Project Figure 1. 2 Light weight materials, a vehicle case study 3 The objective of this project was to make an innovative paper by multi-material and light weight structure.This project proved that, BIW panel structure weight can reduce by 30%, multi material manufacturing with trim cost, recyclability and sustainability of light weight materials. This project was a benchmark performance by joined venture of many sectors and seven vehicle manufactures (including Volkswagen and Volvo), 10 suppliers, 10 R&D companies and seven universities. The final product was a strut of different materials and a wide range of joining technologies. The figure 1. 2 shows the benefits, that Super Light Project achieved.
