UKZN Team: Spray Painting Machine

University of KwaZulu Natal Software: Autodesk Inventor Team:Cameron Pitman, Akshay Maharaj and David Black We were instructed to design a fully automated CMYK spray painting machine. The idea is for the user to select a colour on a computer, and the machine to automatically mix the correct colour and spray paint an object. The system was also required to clean itself. Syringe pumps were designed to dispense the paint, as well as a rotary table to index between stations.

We really enjoyed being able to model the manufacturing processes that would be used to make components and assemble the machine. Modelling using this process ensured that the manufacturing process was as simple as possible and very robust. Inventor’s drawing environment was very simple to use and allowed us to generate manufacturing drawings quickly and effortlessly allowing us to spend more time doing engineering work and less time doing draftsman work.

The user interface is uncomplicated and very user friendly. Learning Inventor is simple and fast. It has many great tools such as the Content Centre and the BOM to name a few which make the design process rapid and save time on project management and admin. The sheet metal environment was particularly useful to the project because laser cutting and metal bending was a large part of the manufacturing process.

University of Witwatersrand Software: Autodesk Inventor For many industries screening is a vital part of manufacturing. Screening, commonly known as sorting, involves the allocation of individual particles of a mixture accordiing to physical dimensions. For very large production systems, such as those at mines and quarries, mechanical vibration screens are often used. A scalping screen was designed with a length of 5.09m, width of 2.60m and height (spring dependent) of 2.42m.

Although it was not required for this particular design project, from previous experience with Inventor I know that I can also do a stress and strain analysis on required parts and assemblies using Inventor if required. In addition to the actual design, the ease at which I was able to create an exploded assembly drawing deserves a mention, it was both logical and amazingly easy. However, the greatest aid in this particular project was the multiple materials available for use within Inventor. This project required the use of multiple steel, plastics and differing rubbers, all of which Inventor possessed.

Vibration motors were utilised creating a varying force of 100kN at an inclination of 45 degrees resulting in a maximum acceleration of 2.66g. The design was created with a multi-deck layout to assist material break-up. The decks involved have maximum aperture dimensions of 40.0mm. The total production cost was estimated at R216 181.80 resulting in a sale price of roughly R450 000.

Using Autodesk Inventor Professional assisted in the creation of my vibrating screen at many points in the design process. The first instance was the ease at which I could create the two screen deck types (one with square apertures, the other with round ones). The second instance involved the ability to create multiple sub-assemblies which could be repeated as necessary in the final assembly of the total mechanism, reducing required tired significantly.

University of Witwatersrand Vibrating Screen Project 2013 3rd year Software: Autodesk Inventor Autodesk Inventor helped me gain a better understanding of 3D modelling that will help me in my future engineering career. The parts list with built in components like bolts, nuts, bearings, gears and circlips significantly cut down my design time and allowed me to spend more time on other more important aspects of my project.

Semi-Automated Beer Production

Semi-Automated Beer Production

University of KwaZulu Natal Final Year Mechanical Engineering Project Software: Autodesk Inventor Group 19 researched, designed and constructed a semi-automated beer production system that produces 40 litre batches of lager craft beer. The processes involved: milling, mashing, filtering, boiling, fermenting and packaging operations amongst others. Extensive research was done into the production of beer and the various processes it involves.

"Inventor provided a platform for the team to model the beer production system which was crucial in order to develop an operational system." (Ryan Dreyer) "I have found inventor very user-friendly, easy to understand, and you can make changes easily. Inventor also includes simulation and analysis capabilities that have enables us to validate our design, particularly designs that required the FEA analysis." (Johannes Angula) Third Team Member: Andrew Illidge

Which aspects of the project are new/unique? To date, Stellenbosch University has conducted research on Stirling engines. This work aims to contribute to two unique research aspects at Stellenbosch University: 1. Development of a Stirling engine, and 2. Integration of a Stirling engine with a small-scale heliostat field. The heliostats will provide concentrated thermal energy as the heat source.

What are the findings? A design methodology for a solar-powered Stirling engines has been developed. Some of the difficulties experienced during construction are brought to light, resulting in a trade-off between theoretical design and practical construction techniques. The engine is now available for experimentation as a learning tool. The benefits and limitations of using solar energy as a heat source have been noted.

Which aspects of the project will carry on after completion? The mechanical movement can be converted to more useful electrical power or connected directly to a mechanical propulsion device such as a pump to get water in remote areas without access to electricity. The operation of the engine can be improved to give a higher efficiency through changes in input parameters. Certain component changes can be implemented to see the effect on the engine output.

The project was significantly made easier by the use of Autodesk Inventor; design accelerator surely accelerated the design of the shaft and gears for the drive system of the vibrating screen. It was just about providing the dimensions of the components, and then the software basically did the rest in terms of producing the required component. The component library that came with the software was quite useful as you just had to search for whatever bolt or shelf available component you would like
