Design and analysis of new suspension system for ultra-light weight green vehicle

Additive manufacturing (AM) technologies provide the possible method to manufacture the new suspension for ultra-weight green vehicles. In spite of traditional suspension system with a large amount of small components, Additive Manufacturing technologies allow the manufacturers to manufacture complicated mechanical structure in single piece which could efficiently decrease the number of components, the mass of new suspensions and the time for assembling. With the support of the modelling software, such as Creo® and AutoCAD®, the design concepts can be easily presented departments and made modifications when it is necessary. Finite element analysis software, such as ANSYS®, will provide the platform to do structural analysis by simulation without physically making the prototypes. Integrating these tools and technologies, time for products development will be dramatically reduced and ready-to-make products can be achieved. In this research, various concepts of the wishbones for the new suspension system will be designed based on the design constraints and the new designs will then be analysed by finite element analysis (FEA) in terms of stress distribution and total deformation of the model under a defined load. Creo® will be used to create the models of wishbones and ANSYS Workbench® will be employed for the structural analysis. Prototypes will also be built by Selective laser melting (SLM).
