- Description: The purpose of this project is to investigate the automotive industry in East London, specifically Mercedes-Benz, in order to propose extensions of the skills development academy and exhibition spaces as an integral part of a larger campus of education. The Mercedes-Benz factory precinct in East London is one of the four largest in the world and is the biggest in Africa, creating grounds for extension. In East London, there is plenty of unemployment and many are seeking jobs in the industrial areas which are mainly automotive. Due to most of the industry being owned by Mercedes-Benz, it is crucial to engage in high levels of education and to provide opportunities for growth within the industry and expansion of skills. Students at the academy will learn different skills in the automotive manufacturing trade and will be guaranteed jobs after their studies are completed. The skills academy will form part of an educational precinct which will establish a narrative for the timeline of Mercedes-Benz. The project will hopefully provide more job opportunities and skills training for the locals of East London as well as to contribute to the economy of the automotive industry. Much like cars, industry works as a machine; there are bits and pieces that need to puzzle together in order to create a working and living machine. The automotive skills academies are exactly that for the industry, a piece of the puzzle which ensures the working of the industry as a whole, now and in the future. Without these skills academies, the automotive industry would subsequently lose its fundamental skills and knowledge base. The core concern for this treatise is the expansion of the industry by creating extensions of the Mercedes-Benz skills academy and creating a space which is educational while being a user-friendly building focused on the wellness of workers and rates of productivity to ensure maximized output and the further growth of the industry. The project is based in East London and will hold a pivotal role in the automotive industry. The treatise looks to break away from the hard industrial aspects of the industry and pull away from the static architecture of Mercedes-Benz and the surrounding buildings, to create a vibrant and experiential building with the overarching emphasis on occupational wellness and innovation in the design. , Thesis (MA) -- Faculty of Engineering, the Built Environment and Technology, School of Architecture, 2021

- Description: This dissertation covers the design and manufacture of an autonomous guided cart (AGC) for use in the material handling industry. General Motors South Africa (GMSA) requires a low-cost AGC for use in their Struandale plant. A budget of R35 000 per unit was proposed. The researcher, in collaboration with staff at GM, compiled a list of engineering requirements for the AGC. After research into the unique problems of the project, an examination of a previous design attempt by staff of GM Thailand, the researcher developed a new design, the subject of this report. Different solutions for each design problem were investigated before the design was finalised. A three-wheeled vehicle was designed making use of two motors in a differential-drive setup to control motion. Navigation is via a line-following mechanism, using an induction sensor-array in conjunction with a pre-laid metallic strip. To aid the design, the system was modelled to understand the different control elements at play. The researcher developed software for several aspects of the design: for the PLC controlling the system and motors; for a microcontroller that communicates with the PLC and a wireless module; for a computer server that communicates with a second wireless device, receiving information from the PLC; and a web interface to view this information. These form the SCADA integration of the project. The final product meets the GMSA specifications. It is a robot capable of towing a trolley of mass not exceeding 350 kg. While the robot is able to navigate a pre-laid route, it cannot reliably stop at marked locations. It is possible to monitor the system via a web-interface. The robot is capable of operating for an entire 8-hour shift before the batteries need to be recharged. The total cost of the prototype was R26 340.

- Description: Bolted connections where used from the beginning of vehicle construction for joining two or more parts. The reliability of bolted connections is still a major problem. The objective of this research thesis is focused on an advanced monitoring system for bolted connections in vehicle construction. A mechanical “vibrating test bench”, which was developed by the aeronautical engineer Mr. Junkers, is being adapted, to suite the requirements of the automotive industry. It is designed according to DIN 65151 standards. The bolted connection is tightened to a specific torque to achieve the required preload forces and then exposed to an oscillating elastic shear force. The preload force and their loss are measured in relation to the number of load cycles. The ideal locking mechanism would be, if no settling occurs. Realistic in practice is the remaining of a sufficient preload force which doesn’t decry with time. The aim of this thesis is, to gain knowledge that will assist in the future control of the bolt locking procedure. The test bench can be used to verify the clamping capability of a bolted connection. With the dynamic computer-aided test system it will also be possible to test critical bolted joints and their safety, which reduces the probability of costly product recalls, or even severe cases of failure.
