Shoulder Motion Simulator Actuator Design
- Developed and evaluated five linear actuator concepts, including a magnetic linear actuator, using weighted decision matrices comparing force output, response time, manufacturability, and system constraints against targets of 140 N force and under 1 kg system mass.
- Produced detailed SolidWorks engineering drawings with tolerances, section views, and assemblies to support design validation and selection of a rack-and-pinion actuator, incorporating DFM/DFA principles to improve assembly efficiency.
Role & Contributions
Contributed to early concept generation, including development of Concept 4 (Magnetic Linear Actuator). Performed concept evaluation using weighted decision matrices to compare actuation methods. Assisted in final concept selection based on performance, manufacturability, and constraints. Produced detailed engineering drawings with tolerances and section views. Contributed to the design plan and validation strategy for the actuator system.
Concepts and drawings
Kinetic Energy Measurement Device for Hailstones
- Designed and built a portable experimental system to measure hailstone kinetic energy prior to ground impact, integrating mass capture, velocity measurement, and energy calculation under a $100 budget constraint.
- Validated accuracy and durability through controlled testing, achieving velocity measurements within a 5.1% standard deviation, a 99% funneling success rate over 150 drops, and an average deployment time of 27 seconds.
Role & Contributions
Conceived the core design concept and led physical prototyping and fabrication. Built the hail collection system and energy measurement apparatus. Assembled and tested the full device, contributing to system integration and validation.
