...ME Analysis Project #2 Christian Seymour Due Date: December 12, 2013 Abstract: The diameter for my shaft design was hand calculated to be 0.8756” for a factor of safety or 2. This factor of safety was expected to be the outcome in FEA SolidWorks and it was not. The reason for this is simply SolidWorks is not the best tool to use for complex designs and loads as ours was. It worked great for the simple beam deflection in the last project. Many times hand calculations are the long way of doing things. In this case, it took much longer to figure out the correct way of adding fixtures, load, and connections in SolidWorks. Many of the material properties in SolidWorks are also not the same as they are in our book. Simply said, choosing which method to use is the hardest decision to make. Sometimes FEA analysis is better, and in some cases, hand calculations are the easiest. Background: We have been given the task to design a shaft to specific guidelines using inch size pillow blocks. We will perform appropriate calculations using modeling techniques and verify the design in SolidWorks FEA program. The problem is 7-5 in the book and is shown below: The problem statement: A geared industrial roll shown in the figure is driven at 300 rev/ min by force F acting on a 3-in-diamter pitch circle as shown. The roll exerts a normal force of 30 lbf/in of roll length on the material being pulled through. The material passes under the roll. Design a shaft for the situation...

...Results and Description For the first part of the experiment, the results were recorded as a table of deflection measurements from each beam resulting from various loads. This table can be seen in Table 1, in Tables and Figures. The data from this table was then plotted using MATLAB. After plotting, trendlines were drawn to model the data. The graph of the trendlines for each beam, as well as their respective equations can be seen in Figure 1, in Figures and Tables. The best representation of the beam’s strength is its Young’s Modulus, or Modulus of Elasticity, which models an object’s resistance to strain under stress. The higher the value of a beam’s Modulus of Elasticity, the stronger it will be. Using the data described above, the Modulus of Elasticity of each beam can be calculated using Equation 1. Table 2, in Tables and Attachments, shows the Modulus of Elasticity of each of the four beams analyzed. For the second part of the experiment, the results of the Finite Element Analysis yielded displacement values in the same way as in the material analysis in part 1 of the experiment. From these displacement values, the same calculations can be made, and non-experimental values for the Modulus of Elasticity of each material result. These values are shown in Table...

...With the emerging importance of CFD and finite element analyses, it is of great necessity that engineering students get a good base of knowledge on one of the most used software packages in the industry of simulation, ANSYS. This brief tutorial states a few simple examples of the main applications of the software package ANSYS and highlights some of the possible problems students may face during their journey in discovering this application. The flow of information is structured that the reader gets an understanding of how important ANSYS is, and how it works and what type of machines are needed for the student level research expected. Then the tutorial goes on with simple straight forward examples of structural and fluid physics simulated using the ANSYS package. Eventually, the tutorial addresses the most important problems generally faced by the students such as unsuccessful meshing, or divergent solutions. Disclaimer It is extremely important to note two points while following this tutorial: The knowledge contained in this paper is by no means, accepted as mainstream, or an industry best practice. It is merely the product of the experience of senior engineering students who explored the program and desired to share their experience with the package. The choices and configurations in every example given are not to be considered as a – one size fits all – template. As the student grows in experience they are expected to try other configurations, commit to trial and error procedures...
