ENGINEERING RESEARCH/PROJECT EXPERIENCE

Finite Element Analysis (FEA) of Aircraft Landing Gear System [Aug 2018 – Dec 2018] Worked in a team of 3 engineers to analyze the main landing gear system of Piper PA-31 aircraft. Solidworks and NX 12.0 were used to model and perform FEA on the system to find which component is most likely to yield in various landing conditions. The ultimate goal of this project was to mitigate the effects of the loads through geometric modification and prevent the failure that may occur in the original model. Target searching Robot Vehicle Development [Aug 2018 – Dec 2018] Worked in a team of 2 engineers to develop and build a robot vehicle that searches for a target object within a designated area, grab the target, and bring it back to base camp. The vehicle distinguishes wanted target among various fake targets and obstacles using a color sensor. Various sensors and actuators were used with 3D-printed chassis to build the vehicle, and the control system including software program and circuit boards were built from the ground up as well.

Stair-lift Rail Generation (T-Rail Generation Program) [Aug 2017 – Jan 2018] Worked with 2 PhD students to develop a program that automatically generates an optimal rail design in each circumstance given. A rail of Stair-lift system, along which the system transfers a wheelchair between floors, is affected by various factors such as the dimensions of staircase, surrounding environment, and customer’s preferences. The developed program reads the surrounding landscape of staircase environment given in DXF format and generates an optimal rail design, which can be directly used for production & installation of the Stair-lift rail, based on input parameters. (sponsored by Thyssen Krupp corporation, manufacturer of Flow 2 Stair-lift) Development of Humanoid Robotic Hand [Jan 2016 – May 2016] Worked in a team of 2 engineering students to develop two different types of virtual models of a humanoid robotic hand for educational use. A MATLAB model was developed to provide Graphical User Interface and help studying complex kinematics of human hand. A Solidworks model was developed to illustrate how the designated degrees of freedom can be realized in a physical model. The Solidoworks model was also used to visualize the appearance of the entire model and detailed shape of each part, and plan manufacturing process of each part.

Advanced Combustion – HCCI Engine [Sep 2013 – Jun 2014] Worked in a team of 4 engineering students to design and built an engine test-bed which can be connected to an engine and gather various data for performance analysis. Designed and fabricated throttle controller and achieved precise reading and control of the throttle angle of the engine. Light Weight Structure [Sep 2012 – Mar 2013]

Designed an Aluminum beam whose cross-sectional area has restricted dimensions and a truss, built with the beam, that can support vertical loads with the minimum weight. Used MATLAB and ABAQUS to analyze the designed system, and ranked 5th place among 30 competitors. Anthopper Olympics 2012 [Mar 2012 – Jun 2012]

Worked in a team of 4 engineering students to design and build a robotic hopper which must race another hopper by hopping back and forth along a designated track. Mainly led the fabrication/testing part of the project, and successfully fabricated the hopper body as designed.
