The Design, Implementation, Evaluation And Results Of A Race Car For The Collegiate Formula Sae Electric Competition, Quinn Jasha Bryan Sullivan Jul 2016

The Design, Implementation, Evaluation And Results Of A Race Car For The Collegiate Formula Sae Electric Competition, Quinn Jasha Bryan Sullivan

Dissertations and Theses

The Formula SAE Electric competition is a collegiate autocross event in which teams design, build, and race an open-wheeled electric race car. The main motivation is the efficiency advantage of electric motors over internal combustion motors. This thesis presents the design and evaluation of two generations of Portland State University electric race cars.

The constraints are the competition rules, finances, human resources, and time required to complete a race car in one year. The design includes the implementation of existing components: battery cells, controllers, electric motors, drivetrains, and tire data for an optimized race car. Also, several circuits were designed ...


Combined Traction And Energy Recovery Motor For Electric Vehicles, James Long, Xin Wang, Claude Kansaku, Brian Moravec Jul 2014

Combined Traction And Energy Recovery Motor For Electric Vehicles, James Long, Xin Wang, Claude Kansaku, Brian Moravec

TREC Final Reports

Electric vehicle manufacturers are looking for ways to optimize energy use for vehicle range extension and reduction of battery capacity. Electric motors have lower efficiencies at very low speed and high torque. This is typically at vehicle launch from standstill, at very low speeds, and during energy regeneration at lower speeds and approaching standstill. The KersTech solution is a breakthrough technology allowing supplement of the electric drive with a hydraulic drive, active in lower speeds ranges, dropping out as the electric motor takes over in its higher efficiency range of operation. The report consists of four parts. Part I presents ...


Evaluation Of The Institute Of Transportation Engineers Program For School Pedestrian Crossing, Nabil S. Hamadeh Jan 1976

Evaluation Of The Institute Of Transportation Engineers Program For School Pedestrian Crossing, Nabil S. Hamadeh

Dissertations and Theses

The Technical Council of the Institute of Transportation Engineers (ITE) developed a program f or school crossing protection. The intent of this thesis is to evaluate the ITE program within. the context of those programs developed by other agencies throughout the nation. Research materials were obtained from the appropriate Federal, state, local and other agencies through papers, articles, reports and correspondence. Upon the analysis of these sources, the ITE program was found to be deficient in several ways. Recommendations for modifying the program which are set forth herein include a revision of the ITE program including the school route map ...
