The model included friction between all contacting surfaces, and also a clearance between the bolt shank and the joint hole. 3D surface-to-surface contact elements were employed to model the contact between the various components of the bolted joint. A three-dimensional (3D) finite element model of the joint was generated, and then subjected to three different simulated clamping forces. The joint consists of three aluminium alloy 7075-T6 plates clamped by a single bolt. In this study, a finite element (FE) stress analysis of aircraft structural double-lap bolted joints was performed using the commercially available computational package ANSYS in order to obtain the clamping pressure distribution and estimate the stiffness of the joined plates (members) within the clamped region. The final design was manufactured and will be a fundamental component of the Race Car as from the Formula Student 2021 competition due to the cancellation of this year’s event. It was then possible to provide the manufacturer with a technical drawing to produce using CNC machining. This decision proved appropriate at a later stage when it was decided to use the wheel hub from last year’s car.Ī final wheel centre model was completed and verified. This was achieved choosing the Aluminium Alloy 6082-T6 along with weight- saving techniques on the design, which gave a final mass of 861.9 Kg.Īmong key decisions made during this project, the main one was the choice of using wheel lug bolts and nuts for the attachment of the wheel to the wheel hub, instead of a single wheel nut. Another objective set for the wheel centre was a mass below 1 Kg. The key objectives were to match the requirements of a chosen wheel rim, cooperating with members of the team working on the components to be located inside this wheel and to verify all the dimensions to avoid future issues. In particular, the focus of this project is the creation of a wheel centre which was designed and analysed in an FEA on Solidworks 2019, after performing fundamental calculations of different loading cases that a wheel can be subjected to in a racing competition. The purpose of this study is to provide the Formula Student Race Team of the University of Nottingham with a design of a 13” three-piece wheel.
