There is a growing need for improved conceptual vehicle designs along with alternative materials to reduce the damage to the passengers and structures in aerospace and automotive industries. The energy absorption characteristics of materials play a major role in designing a safe vehicle for transport. In this paper, compression behavior and energy absorption of aluminum alloy AA6061 and AA7005 tubes in T4 and T6 conditions are investigated by experimental and numerical methods. The AA7005 and AA6061 tubes are solution heat treated and then aged to achieve the final strength in T6 condition. Experimental compression test results have shown improved energy absorption of tubes in T6 condition compared to tubes in T4 condition. There is less variation of energy among the tested samples. The mean load is compared with the results obtained from analytical formulas. Tensile properties have been obtained from tensile tests using UTM for both AA6061 and AA7005 tubes.

In the recent Past the automobile Industry have been focusing on Cost reduction and Quality Improvement. Ashok Leyland DOST- Engine has been designed with the motto of developing engine of Japanese Quality at Indian Cost. An Aluminum Alloy Cylinder Head has been designed & developed for this application through an Innovative and Efficient approach for the Cost Centric & Quality Conscious Indian Market. This is a first Aluminum 3-Cylinder Head developed for LCV application in India. Robust design process has helped us in achieving industry benchmark of BS4 emission with 2-Valve per Cylinder arrangement itself. In order to keep the tooling Cost minimum, the Cylinder Head has been manufactured using "Tilting GDC" Process. The selected material combined with apt Heat Treatment has eliminated the need of Bearing for the Single Overhead Camshaft. An Innovative approach for Compactness has been achieved by Mounting the Fuel Pump Housing , Tensioner and Common rail on the Cylinder Head.

AMSQQA200/11A
This specification covers the specific requirements for aluminum alloy 7075 bar, rod, shapes, tube, and wire produced by extrusion. AMS-QQ-A-200/11A has been declared "STABILIZED" by AMS Committee D. This document will no longer be updated and may no longer represent standard industry practice. This document was stabilized because it contains requirements that are no longer state of the art and are also contained in alternate documents that contain equivalent requirements. Previously this document was reaffirmed. AMS Committee D has never performed a technical update of this document. Users of this document should refer to the cognizant engineering organization for disposition of any issues with reports/certifications to this specification; including exceptions listed on the certification. NOTE: In many cases, the purchaser may represent a sub tier supplier and not the cognizant engineering organization.

Abstract Aluminium alloys have been used extensively in the automotive industry to reduce the weight of a vehicle and improve fuel consumption which in turn leads to a reduction in engine emissions. The main aim of the current study is to replace the conventional cast iron rotor material with a lightweight alternative such as coated aluminium alloy. The main challenge has been to meet both the cost and functional demands of modern mass-produced automotive braking systems. A sensitivity analysis based on the Taguchi approach was carried out to investigate the effect of various parameters on the thermal performance of a typical candidate disc brake. Wrought aluminium disc brake rotors coated with alumina on the rubbing surfaces were determined to have the best potential for replacing the conventional cast iron rotor at reasonable cost. Optimisation of the structure was subsequently carried out using a genetic algorithm on the selected coated aluminium disc brake rotor.
