MY THESIS PROJECT MODEL

 CHAPTER FIVE: IN PARTIAL FULFILLMENT

Undergraduate Thesis Machine Model: The Motorized Torsion Testing Apparatus


An Abstract of The Machine

A motorized torsion testing machine capable of determining the shear properties of materials according to American Society for Testing and Materials (ASTM) specifications was developed. The machine provided an economical, accurate, less laborious, and fast means of performing the standard ASTM torsion experiment on the specimens used. It also provided opportunity to study the specimens under torsion. Fundamental design analysis and calculations were carried out in order to determine and select materials of appropriate strength and sizes for the machine components. 


This design was made and fabricated by my project group, led by me. The machine was later installed in the school's mechanical/materials testing lab for conducting Non Destructive Tests (NDT) on the specimens of engineering materials for student labs. We had an 'A' in the project and it was also among the top rated of all other students theses that year. 

    After an extensive literature review on school lab material testing machines, the design was thus inspired by the need to improve on some major challenges facing material testing such as: a lack of ASTM standard torsion testing of engineering materials due to costliness of torsion machines. Again the existing manual torsion testing process of using dead weights/masses is time wasting, laborious and energy consuming, especially if a lot of materials need to be tested. 

    Hence the novel apparatus we came up with addresses these issues by introducing a motorized (electric motors) operation to it, thus saving time and energy, while also lending itself to a futuristic interfacing with a computer. This will electronically collect the results of such testing operations and use it to plot relevant graphs, such as the stress-strain graphs.

NB: The model was made with Solidworks.

THE CENTRIFUGE DRIER

Image
 CHAPTER THIRTEEN: THE CENTRIFUGE DRIER From our laboratory chemistry we all know what a centrifuge is and what it does, and how it does it. A centrifuge is a device in which a mixture of denser and lighter materials (normally dispersed in a liquid) is separated by being spun about a central axis AT HIGH SPEED. Yes! I had to capitalize that, for it is in its great rotary speed that the centrifuge achieves its primary task of separation.  In this particular machine, same high speec principle is used to dry, instead of separate. A typical real life application of this is our washing machine. During the drying stage of the laundry, the machine spins at very very great speeds, that throws out moist from the fabric. In the very same way, the machines dries inputs to it.  The machine full set up is not completed yet though.

FIBRE SEPARATOR

 CHAPTER TWELVE: THE FIBRE SEPARATOR This machine is yet another player in the family of Oil milling industry and machines. After the digester press is done extracting the pulp from the palm fruit, the by-product of the palm kernel and its fibres are next received by this machine. Like the name goes, the FIBRE SEPARATOR sifts the mixture of palm kernel and its fibres. The fibre chaffs drops down, through a hole under the machine, while the unshelled nuts comes out through the outlet in front of the machine.  See model views and dimensions.

THE FEED MILL EXTRUDER

Image
 CHAPTER ELEVEN: THE FEED MILL EXTRUDER The Feed mill Extruder is an agro-industrial machine for processing feed for livestock such as fishes and poultry. It uses multiple combination of electric motors that drives a screw conveyor, to press a feed mixture through a series of tiny perforations at the end of a heated and insulated drum. From the other end of the drum, a delicious, attractive strip of pasta (like your spaghetti), is forced out. After drying the pasta, it becomes hardened and crispy; it is then bagged and ready to be served to your livestock.  Facing/adjacent to the extrusion orifice of the drum is a smaller motor powering a rotary cutter that slices the extruded continuous strip of pasta as they form out of the chamber.  Enjoy the some of the views of this awesome industrial machine that I have drawn.  😀😀.
