![]() ![]() Numerical analysis was performed in the ANSYS software package. First, the input data for the numerical analysis was calculated. Structural analysis of the clutch was performed by using the finite element method for a repressive vehicle example-TATA Sumo. Especially, the precise prediction technique of maximum structural stress should be requested in design of mechanical clutches for. In design of the friction clutches of automobiles, knowledge on the thermo-elasticity a priori is very informative in the initial design stage. This paper presents the stresses and deformations of the automotive single plate clutch depending on the applied materials. The material considered for the design of the rear upright was Aluminium Alloy 7075-T6 as it has superior mechanical properties in terms of stiffness, fatigue and tensile strength for the application compared to both the Alumec alloy and Aluminium Alloy 6061-T6 considered in this paper. Other relevant analysis were presented, such as sphere of influence and exaggerated deformation which showed that the upright will experience a maximum deformation of 0.132mm during the worst case lap scenario (left hand turn). For the fatigue analysis on the brake calliper mount, the resulting safety factor plot presented a minimum factor of three for infinite life. For single bump loads, the upright could withstand a vertical bump load of stress value significantly lower than the ultimate tensile strength. For the fatigue loading of the whole upright, it was observed that the greatest stress throughout the four drive cases occurred in a left hand turn. They include fatigue of upright, single bump loads and the zero-based fatigue loading of the calliper-mounting bracket. workbench, three main load cases with combination of drive cases (acceleration, braking, and left and right turn) were used to evaluate performance of the rear upright. To ensure optimal design with the aid of Finite Element Analysis using ANSYS. This paper details the design of rear upright for a JCU Tec-NQ (JTR) Racing Motorsport, Formula Society of Automotive Engineers (FSAE) race car using Aluminium Alloy 7075-T6 through the use of a track simulator developed by RMIT Racing, forces on the upright were calculated and an upright was designed in SolidWorks. Moreover, some beneficial longitudinal compressive stresses were observed around the fastener hole as a result of the clamping compressive effect. FE results revealed an overall crock-shaped pressure distribution at the joined plates. 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.
