Alternative up-step to rear deck

Abstract [en]

This project is carried out in the frame of a master thesis at the initiative of Volvo 3P, dept 26441 Chassis Equipment. The main goal of the project was to design an alternative solution to the up-step to the rear deck, aimed at the next generation of trucks. The rear deck has to be accessed when the trailer is connected/ disconnected. The project was divided into four blocks, a pre-study phase, two concept phases and a final concept phase. In the pre-study phase 12 concepts were generated through brainstorming. For the evaluation a pugh matrix was used. The different concepts were assessed after selected criteria, which were given weight factors based on their importance. Through the following two concept phases the number of concepts were narrowed down and finally one concept remained. The final concept is a ladder fitted under the rear deck, which can be extracted for usage. The final concept was modelled in Pro/Engineer and FE-analysis were conducted by using Pro/Mechanica. The final design solution is a sheet metal ladder in a protective box. Three steps are placed equally. For all chassis heights above medium a extra telescopic step has to be used to fulfil the requirements. The box serves as rails and also protects the ladder from dirt, snow and ice. The material chosen for the design is a high strength stainless steel. The design fulfills most requirements set in the early stage of the project except for the weight. There are given some suggestions how to minimize the weight, and also some other suggestions for future work. During the concept phase several new ideas came up but it was decided not to put any effort in developing these. They are mentioned in the report.
