1- Senior Design Project (Ring expansion testing & fatigue analysis of steels). ( Jan 2019 – Dec 2019 ) Project description : - A two-way ring expansion method was developed to determine the mechanical properties specifically the ultimate hoop stress (UTS) of a ring. - FEA software ABAQUS was used to analyze the test and check its validity and limitations. - The Parts of the expansion test were manufactured to conduct the experiments. - Implementing a study on fatigue behavior of steel shafts undergoing cyclic loading with different load arrangements. - FEA software ABAQUS and module FE-safe were used to compare the analytical solutions with the numerical one. 2- Design a color sorting mechanism. ( Nov 2019 – Dec 2019 ) Project description: - our design consists of two servo motors, a color sensor, and a wood frame with a special design to fulfill the color sorting mechanism. - We used the ARDUINO program to write the code by using c++ language which satisfies the sorting mechanism and managing the required delay for each angle of rotation of the servo motor. 3- Design a 3-Degree OF freedom robotic arm has attached a horizontal platform. (Mar 2019 – Apr 2019) Project description: - The purpose of this project is to control a 3 DOF robotic arm that can move an object from one place to another one and the wood platform stays stable in a horizontal plane. - Our design consists of an MPU-6050 sensor, 4 servo motor, an Arduino board, a Bluetooth module, and a Wood platform. we used the ARDUINO program to write the code by using c++ language, MPU-6050 sensor, Bluetooth module, and LITTLE A RM APPLICATION to control our robot. 4- Design of a solar heating system using a flat plate collector. (Mar 2019 – Apr 2019) Project description: - The best location and orientation of the flat plate collectors were found based on the sun’s location relative to a specified longitude and latitude. - Finding the slope and intercept of the collector based on given specifications. - Determining the number of collectors that cover a specified portion of the required load. 5- Design of a quick return four-bar slider-crank mechanism. ( Feb 2018 – Apr 2018 ) Project description: - Advanced excel functions and operations were used to complete this project. - This project includes the study of the effect of linkage sizes on the torque fluctuation.
