Resumen: Public Service Vehicles (PSV) are very efficient means of mass transportation both in terms of energy consumption and environment pollution per passenger kilometre. The renewal of PSV represents a high capital investment and thus lengthening the operational life of the vehicle will bring benefits not only to the operators (through reduction of capital and running costs) but also to society (through conservation of energy, raw materials and environment protection). The structural frame of a typical interurban bus weights between 2000 and 2300 kg. Since the frame must provide the needs of strength, stiffness, crashworthiness and corrosion resistance it is a prime target for improvement. The project had as its main airo the production of a concept frame cell for PSV vehicles in aluminium alloy using adhesive bonding technology as the joining method. It was an integrated, multidisciplinary project in that it covered the materials selection, design manufacturing processes and application requirements dictated by relevant international regulations. The major objectives ofthe project were: -Overall geometry ofthe structural cell must comply with ECE 36 regulation -Strength and stiffness must not be less than that currently specified for steel structures -Airo for a 45% weight reduction -Crash resistan ce in rol! over accidents in accordance with regulation ECE 66 -Development of simplified theoretical tools for crashworthiness analysis -Cell structure and joints durability under fatigue load and corros ion resistance adequate for long term application -Ease ofmanufacturing and cost effective fabrication
