USS Zumwalt Personal Project Report I am proud to have selected the USS Zumwalt Destroyer-Class vessel to fully model on Solidworks. I chose this specific object, the original Zumwalt-Class Destroyer USS Zumwalt DDG-1000, because it relates to my current and future lifestyle. I am in Penn State’s Navy ROTC unit on a full scholarship, which pays for y entire tuition plus special stipends. This means, however, that after my four years of education, paid for by the Navy, at Penn State I will be commissioned as an officer into the United States Navy. The USS Zumwalt model represents my passion for my current role in the United States Navy and my future career as a US Naval Officer defending my country. The Zumwalt-Class Destroyer especially interests me in the service that I am in because it is the newest vessel class to be commissioned by the Navy. It has a high-tech radar and gun system that is pinpoint accurate and its hull (or main body) is designed so that it is not detectable on many types of radar and location systems. Thus, this Solidworks project of modeling the USS Zumwalt was selected because it perfectly melds my passion for the Navy and interests me personally as an engineer because of the new technologies and designs that went into its original building. I used many features to complete this project as many of the parts in the assembly required special features to create as close to the original as possible. The USS Zumwalt Solidworks model I built was built with five separate main parts. First, the main body of the ship, or the hull, was the most complicated and time consuming part. I first traced out the initial hull shape from the reference above. When I finished designing and dimensioning the main hull, I used a simple “Extrude Boss/Base.” This create a solid, 3D hull which I was able to shape how I liked. I used the “Reference Geometry” feature to create a new plane and designed a way to where I could make an “Extruded Cut” diagonally along the stern (rear) of the hull. This is why the bottom of the ship near the back is curved. The next part of the process was creating the triangular, sloping front of the hull. This required three new planes created from the “Reference Geometry” feature and separate sketches for both sides of the ship. When all of these lofted sketches were finished, I used the “Lofted Cut” mechanism to create a smooth, rounded side of the hull, very similar look to the original style of the ship. I then used several “Fillets” to create an even more pronounced curvature. Finally, I added several “Extruded Boss/Base” functions to create the keel and propeller on the stern of the hull. The next part I had to work on was the deck house, or the large block on top of the hull that houses many of the shipboard technology and living accommodations. This required more “Extruded Boss/Base” functions to create the main design of the deckhouse, and then a series of “Lofted Cuts” to create the sloping style at the front end of the deckhouse. Next, were the onboard gun systems. I made two different sizes of the gun systems onboard, but both were created with a pair of extrudes. Finally, the last main part that I used Solidworks features on was the flagpole. I used a “Sweep” to create the flagpole and added the flag as a picture from file. I also added some other decals while “Mating” the assembly, but all of the decals do not show up during the rendering process. The toughest and most trying part of the Solidworks project was designing the triangular, sloping design at the bow (front) of the ship. This required almost 4 hours of devoted time to figure out how to use different functions and how to design it perfectly. In all, the design required three sketch re-designs of all of the sketches to remove the “Zero Thickness Geometry” error. I learned how to create “Lofted Cuts” in this tough portion, which I did not know how to do initially. I also learned how to use Solid works to automatically solve dimensioning issues to expedite the design process. The Solidworks portion of this class truly taught me how engineers use computer models to take their creations from 2D paper designs to 3D models. I interned at the American Bureau of Shipping (ABS) in Alexandria, Virginia for three weeks about a month before coming to Penn State. In that internship, I often saw computer models of ships that I was regulating and learning about, since ABS does a lot of its business with commercial ships and the United States Coast Guard. With the tutorials, mini project, and personal project on Solidworks in this class, I finally understood the amount of time and effort required to create computer models like the ones I saw in my internship. This project is a building block that I can use in the US Navy as an engineer and when I enter the civilian engineering field.
