Below are samples of Brandon Marambas previous modeling work generated by using the computer aided design program SolidWorks. Rotary Pressure JointThe objective of this project was to generate a Rotary Pressure Joint model using handouts pictures and dimensions given by the computer aided design professor. Another objective was to utilize SolidWorks modeling program to create an assembly and detail drawings of the Rotary Pressure Joint. As seen in Figure 6, the project involved the creation of ten different components, Body, Head, Nipple Tube, Nipple Body, Thrust Collar, Seal Ring, Spring, Gasket, Key, and HBolt. The creation of the Rotary Pressure Joint used very advance command features such as BLEND, MIRROR GEOMETRY, HELICAL SWEEP, and EXTRUSIONS. The assembly involved the mating of ten different components to form one cohesive piece. The commands, COINCIDENCE OF AXIS and SURFACE COINCIDENCE, was very useful in creating of the final product. Shown below is Figure 1: Solid Model View, Figure 2: Bottom View, Figure 3: Top View, Figure 4: Section Cut View, Figure 5: Exploded View, Figure 6: Detailed Drawing of Components, and Figure 7: Detailed Drawing of Head Component. Comments: Creating the Rotary Pressure Joint seen in Figure 1, 2, 3, 4 and 5 was challenging and took the culmination of all the skills I have learned in my computer aided design class. The project involved numerous steps, but was rewarding to see the completion of final product.

This model can be constructed by following the SolidWorks predator drone tutorial the professor sent to the class. The model involved the creation of main four parts, Drone Body, Propeller, Hell Fire missiles and Launcher. Modeling the drone was unique because each part was created through a set of XYZ data points. The creation of the Predator Drone used command features such as CURVE THROUGH XYZ POINTS, LOFTED BOSS/BASE, MIRROR GEOMETRY, REVOLVED BOSS/BASS, and SPLINE. The assembly involved mating the Drone Body, Propeller, Hell Fire and Launcher to form one piece. The use of the commands, COINCIDENCE OF AXIS and SURFACE COINCIDENCE, made the creation of the final product easier. Please refer to Figure 8 (Top Isometric View), Figure 9 (Bottom Isometric View), Figure 10 (Drone Propeller), Figure 11 (Front Body Section), Figure 12 (Rear Body Section), and Figure 13 (Zoomed in View of Pylon, Launcher and Hell Fire Missiles) for beter inspection of model.Comments: To create the body of the Drone, the use of x, y, z notepad data points for the body spline and the LOFTED BOSS/BASS command was key on modeling the part. To create an accurate airfoil for the wing sketch, download the Clark YS Airfoil excel data points found in UIUC Airfoil Coordinates Database and convert the excel data points into notepad. Using the MIRROR command saved time creating this model.

Car Wheel The mission was to independently create a unique car wheel design, seen in Figure 14, by using SolidWorks. The model can be constructed by following the SolidWorks tutorial the professor sent. Referring to Figure 14, the model involved the creation of three parts, Tire, Car Rim, and Hub Cap. After creating these three parts, the task was to assemble the components to form one Car Wheel. The creation of the Car Wheel used commands such as REVOLVED BOSS/BASS, CIRCULAR PATTERN, VERTICAL CENTER LINES, OFFSET ENTIRES and CONVERT ENTRIES. Below contains Figure 14: Exploded View of Car Wheel, Figure 15: Solid Model of Car Wheel, Figure 16: Front View of Car Rim, Figure 17: Isometric View of Tire and Figure 18: Isometric View of Hub Cap. Comments: The Car Rim in Figure 16 involved using REVOLVED BOSS/BASS, CIRCULAR PATTERN, and VERTICAL CENTER LINES commands to create the pattern design and rim.

Figure 18: Isometric View of Hub CapSteady State Thermal Analysis of Heatsink The assignment was to run the steady state analysis with heat load of 50 watts and a constant convection coefficient of 100 W/m2 C due to force convection of air flow in cooling the system using Simulation in SolidWorks. Heatsink was assigned a material, Aluminum Alloy 2014 Alloy. Steps to create the results seen in Figure 19:Step one, split the bottom face of the Heat Sink by SKETCHING a square and the selecting SPLIT LINE to sketch out the CPU. Step two, transfer the model to Simulation by clicking on the SIMULATION tab. Step three, create a new thermal study by clicking NEW THERMAL STUDY, and assign the Heat Sink a material. Step four, place 50 watts in the split square(cpu), using HEAT POWER. Step five assign a CONVECTION CONDITION to all the surfaces expect the split square and then select CREATE MESH. Step six, make sure the mesh density is all the way to the right on FINE MESH. Step seven, select run STUDY to see temperature distribution. Please refer to Figure 19 (Image of Temperature Distribution of a Heatsink) to see results of test. Step eight, right click on IMAGE 1(STUDY RESULTS) and click SECTION CLIPPING to clip the section. This will clip a section of the Heat Sink for the report. Step nine, generate report by clicking Report. This will collect all the test data and automatically generate a report. Comments: This assignment teaches how to create and perform Steady State Thermal Analysis on any model and how to generate a report of the results using SolidWorks.

Figure 19: Image of Temperature Distribution of a Heatsink Fluid Simulation in a Square Duct The assignment for the Square Duct was to use SolidWorks Flow Simulation to study the Pressure contours plot at symmetry plane, Velocity contours plot at symmetry plane, Velocity vector plots at symmetry plane, Surface Plot, and Flow Trajectories as water flows though the model. After analyzing the Square Duct, the task is to then generate a report of all the data using SolidWorks. Figure 20 shows the results of the Flow Trajectories. Comments: This assignment teaches how to create and perform Flow Simulation on any model and how to generate a report of the results using SolidWorks.
