Nufotec is a company that works with mechanical design and product development. The company has worked with a Tranås based company called Inzile in the past. Inzile has built small electrified trucks in the past but are now going to start development of electrified resort vehicles. In 2022 Inzile was acquisitioned by a Spanish company which got Inzile to change track and because they had never built a vehicle like this before, Nufotec was tasked to help. Nufotec works with many parts on the project and the large project has been scaled down to smaller parts, which are to be combined to generate a good final product. The project group who writes this study has been assigned a part problem on the large project. The part problem which this study points to, is to join a superstructure of aluminum and a galvanized steel structure. The result which is to be presented is two to three final concepts where joining method, corrosion and loads are considered. The study revealed a large risk of corrosion and because of this a decision was made to eliminate this risk, the decision was to isolate all dissimilar metals from each other. Different joining methods was considered in the study, and it appeared that bolted joints were the best. To test the different concepts, they were put through FEM simulations. This shows where stress and deformation will occur and gives an estimate of what the concepts can withstand. After the simulations, the concepts went into an elimination matrix and the two remaining are the final concepts. |
