Computer Aided Design/Modeling/Simulation Projects
My CAD projects have been mostly done in CATIA V5 and SolidWorks. I love designing with computers, and I have spent some of my free time designing various objects and devices in CATIA and SolidWorks. Most of my designs are available for inspection and download from GRABCAD, in which I have an account, and I usually upload my models there. A few of my designs in CATIA and SolidWorks can be seen below.
This was my first attempt at complex surface design in CATIA, early in 2013. I made the fan blades using the tools in the Wire-frame and Surface Design and Generative Shape Design sections of CATIA V5 R21. Then, I used the DMU Kinematics workbench to animate the fan around its own axis. This simple fan can be used in numerous other CAD projects as well.
This model was a slightly more complex attempt at Generative Shape Design in CATIA V5 R21. All of the turbine's blades have been designed in Generative Shape Design environment, then turned into a solid part. The part features complex curves in a 3D space made using drawing wire-frames across 3D guide curves.
Sheet Metal Punch and Die
This features a sheet metal in a rather simple shape, being produced by punch-and-die. I designed the punch and the die, and the software produced the product. CATIA has a special workbench for Sheet Metal Design and all of its related operations regarding welding, manufacture, and so forth. This model is also available for inspection and download here.
Design and Structural Analysis of a Helical Gear
This project has been made in CATIA V5 R21. You should know, I am able to design all sorts of mechanical parts such as gear trains in CATIA and SolidWorks. This was my first attempt at creating a gear in CATIA, and also structural analysis of a gear in CATIA. A uniform force and torque is applied on the gear, as it would for a normal realistic helical gear working in steady constant operation.
This was when I was studying the concept of Gyroscopes in Dynamics (2) course in B.Sc. It has been fully designed and assembled in CATIA V5R21. The design of the central part was harder than the rest. The gyroscope is dynamic, and all of its three rotors can move freely. This makes this part a handy tool in trying one's hand at dynamic simulation or animation. STEP and IGES parts are also available for this model, should one need to work on this model in SolidWorks or other applications.
This, at the time, was my CAD masterpiece. This clock is sitting on my desk right now. I reverse-engineered it and re-designed it in CATIA V5R21. All of its parts are dynamic and free-moving, making this clock a very handy CAD model for anyone trying to try their hand on dynamic simulation or animation. This was by far the most detailed model I had ever designed.
Computer Simulation of a Fan
In this project I used C++ coding in tandem with the OpenInventor C++ library, derived from OpenGL. A pushbutton action would increase and decrease fan speed. In addition to animating the rotation of the fan, it is capable of being actively rotated and panned, with its rotation speed being demonstrated on the console generated by C++
Computer Simulation of Cycling Motion
This project is similar to the previous one, except the fact that it works on the cycling motion of a human lower-body skeletal model. It uses the same OpenGL library in C++. It should be noted that the reason why more modern and complicated graphics libraries and software were not used, was that computer-based modeling was meant to be practiced in a low-level computing language such as C++, and coding in OpenInventor is much easier than other graphics libraries such as Blender, Qt, etc.
