LOW WEIGHT VEHICLE - MANUFACTURING ASPECTS OF ALUMINIUM BODY STRUCTURES

Objective


Guidelines have been established, classified and published: they have covered most of the situations which will occur in a real mass production.

The potentiality of all the forming assembling processes has been evaluated and compared mainly on technical level.

The economical approach is more difficult. Gained data have to be reconsidered taking into account the in-house policy of each car manufacturer.
To decrease the fuel consumption of vehicles, one of the most efficient methods is to decrease their weight. Aluminium is a promising material to achieve this goal. The main problems to be solved concern the industrial manufacturing of aluminium cars, especially with the concept of the space frame. This project deals with the main problems related to industrial production: production rate, feasibility, processes for producing parts, proposal of innovative solutions and attemps to validate them.

The main topics of this project are:

- forming of aluminium sheets for sheet nodes and structural large parts,

- evaluation of casting processes to achieve industrial production of cast parts, these parts having suitable properties,

- forming of profiles in order to realize a real space frame,

- assembling the profiles: either directly or by means of sheet or cast nodes, the joining process being either welding (MIG, TIG, laser, spot welding), adhesive bonding, mechanical joining or a combination oftwo of these processes.

All the activities of this project are closely linked and also with the other projects of the Targeted Research Action: LOW WEIGHT VEHICLE-MATERIAL AND STRUCTURE. All the research activities proposed in this project have an industrial goal in view of a short term application.
