Collision Mitigation System: Pedestrian Test Target, Final Design Report, Timothy Ryan Lee, Melanie Lim, Tiffany Margaret Prather, Chris Michael Welch

Mechanical Engineering

Daimler Trucks North America is creating an advanced emergency braking system which uses radar sensors that detect pedestrians and automatically applies the brakes to bring the vehicle to a stop. To improve and validate their technology, they need a mechanical pedestrian target that can mimic a human walking across the street. However, the assisted braking may not work properly during every test and the pedestrian target must be able to survive impact with a vehicle at low speeds. Four senior Mechanical Engineering students from California Polytechnic State University San Luis Obispo decided to take on the challenge.

Finite Element Modeling Of Delamination Damage In Carbon Fiber Laminates Subject To Low-Velocity Impact And Comparison With Experimental Impact Tests Using Nondestructive Vibrothermography Evaluation, George Rodriguez Iv

Master's Theses

Carbon fiber reinforced composites are utilized in many design applications where high strength, low weight, and/or high stiffness are required. While composite materials can provide high strength and stiffness-to-weight ratios, they are also more complicated to analyze due to their inhomogeneous nature. One important failure mode of composite structures is delamination. This failure mode is common when composite laminates are subject to impact loading.

Various finite element methods for analyzing delamination exist. In this research, a modeling strategy based on contact tiebreak definitions in LS-DYNA^®was used. A finite element model of a low-velocity impact event was created to …

Physical Testing Of Potential Football Helmet Design Enhancements, Michael Jeremy Schuster

Master's Theses

Football is a much loved sport in the United States. Unfortunately, it is also hard on the players and puts them at very high risk of concussion. To combat this an inventor in Santa Barbara brought a new design to Cal Poly to be tested.

The design was tested in small scale first in order to make some preliminary conclusions about the design. In order to fully test the helmet design; however, full scale testing was required. In order to carry out this testing a drop tower was built based on National Operating Committee on Standards for Athletic Equipment, NOCSAE, …
