Development Of A Hybrid Vehicle Powertrain Test Laboratory, Bennet Samuel Soundarraj
Doctoral Dissertations and Master's Theses
During the last two years, Embry-Riddle Aeronautical University has installed and tested a fully functional eddy-current chassis dynamometer testing facility on campus. An automotive test facility requires a systems engineering approach to install, calibrate and commission a chassis dynamometer. This thesis shows that, the dynamometer test facility was successfully installed, commissioned and documented to safely support the power train development and testing. We can currently test the EcoCAR vehicle and a number of other front-wheel-drive vehicles at our university campus using the eddy current chassis dynamometer.

Loading Path Determination For Tube Hydroforming Process Of Automotive Component Using Apdl, E. Masoumi Khalil Abad, Amir Ghazanfari, R. Hashemi
Faculty Publications, Mechanical Engineering
In this study, an extended stress-based forming limit diagram (FLD) for prediction of necking based on the Marciniak and Kucznski (M-K) model is represented and applied in tube hydroforming. The bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. This adaptive simulation technique is based on the ability to detect the onset and growth of defects (e.g., bursting and wrinkling) and to promptly readjust the loading paths. Thus, a suitable load path is determined by applying Adaptive Simulation Method in ANSYS Parametric Design Language (APDL).

Use Of A Rolling Road System In Crosswind Conditions, Mau-Kuo Chen
Use Of A Rolling Road System In Crosswind Conditions, Mau-Kuo Chen
Mechanical & Aerospace Engineering Theses & Dissertations
Wind tunnel testing continues to play an important role in vehicle aerodynamic development. Accurate results are strongly associated with whether the wind tunnel can closely simulate the on-road conditions, including the Reynolds number and all boundary conditions. Rolling road systems (or moving belts) have been a successful tool for many auto makers and racing teams to simulate the relative motion between the stationary vehicle model and the floor in the test section. The mechanism of the rolling road system is simple, but how it affects the adjacent flow field and how this flow interacts with the flow underneath the vehicle …

Identifying factors that affect crash injury severity and understanding how these factors affect injury severity is critical in planning and implementing highway safety improvement programs. Factors such as driver-related, traffic-related, environment-related and geometric design-related were considered when developing statistical models to predict the effects of these factors on the severity of injuries sustained from motor vehicle crashes at merging and diverging locations. Police-reported crash data at selected freeway merging and diverging areas in the state of Ohio were used for the development of the models. A generalized ordinal logit model also known as partial proportional odds model was applied to …

Impact-Acoustic Evaluation Method Of Internal Crack In Rubber Composite Structure, Qin Shen
Impact-Acoustic Evaluation Method Of Internal Crack In Rubber Composite Structure, Qin Shen
All Dissertations
The main objective of this work is to investigate the impact acoustic method as a means of nondestructive testing (NDT) for internal cracks in a rubber composite structure, such as that found in a tire. As demonstrated in this dissertation, this approach is an effective and economical alternative to the current NDT methods for tires casing integrity inspection. There are two separate aspects of the impact acoustic signals considered in this work: the impact force signal and the resultant acoustic signal. First, a contact dynamics model is developed based on the Hertz’s impact theory and modified for rubber composite materials. …
Unmanned Ground Vehicle Navigation And Coverage Hole Patching In Wireless Sensor Networks, Guyu Zhang
Unmanned Ground Vehicle Navigation And Coverage Hole Patching In Wireless Sensor Networks, Guyu Zhang
Doctoral Dissertations
This dissertation presents a study of an Unmanned Ground Vehicle (UGV) navigation and coverage hole patching in coordinate-free and localization-free Wireless Sensor Networks (WSNs). Navigation and coverage maintenance are related problems since coverage hole patching requires effective navigation in the sensor network environment. A coordinate-free and localization-free WSN that is deployed in an ad-hoc fashion and does not assume the availability of GPS information is considered. The system considered is decentralized and can be self-organized in an event-driven manner where no central controller or global map is required.
A single-UGV, single-destination navigation problem is addressed first. The UGV is equipped …

Tdma Slot Reservation In Cluster-Based Vanets, Mohammad Salem Almalag
Computer Science Theses & Dissertations
Vehicular Ad Hoc Networks (VANETs) are a form of Mobile Ad Hoc Networks (MANETs) in which vehicles on the road form the nodes of the network. VANETs provide several services to enhance the safety and comfort of drivers and passengers. These services can be obtained by the wireless exchange of information among the vehicles driving on the road. In particular, the transmission of two different types of messages, safety/update and non-safety messages.
The transmission of safety/update message aims to inform the nearby vehicles about the sender's current status and/or a detected dangerous situation. This type of transmission is designed to …

Study Of Syngas Combustion Parameters Effect On Internal Combustion Engine, Ftwi Yohaness Hagos, A. Rahsid Abd Aziz, Shaharin A. Sulaiman
Ftwi Yohaness Hagos
Syngas is considered to be a viable alternative fuel to fossil derived fuels in both gas turbines and reciprocating gas engines. Detail studies of syngas as a dual fuel in compression ignited engine, diesel as a pilot fuel and as a single fuel in a naturally aspirated spark ignited engines are found in the literature. Even though the prospect of fuelling naturally aspirated spark ignition engine with syngas is very promising and even cost competitive with that of natural gas, it is associated with power de-rating that is mainly provoked by the decrease in volumetric efficiency. With the advancement in …

Indeterminate Masses, Elements And Models In Information Fusion, Florentin Smarandache
Indeterminate Masses, Elements And Models In Information Fusion, Florentin Smarandache
Branch Mathematics and Statistics Faculty and Staff Publications
In this paper at the beginning, we make a short history of the logics, from the classical Boolean logic to the most general logic of today neutrosophic logic. We define the general logic space and give the definition of the neutrosophic logic. Then we introduce the indeterminate models in information fusion, which are due either to the existence of some indeterminate elements in the fusion space or to some indeterminate masses.
The best approach for dealing with such models is the neutrosophic logic, which is part of neutrosophy. Neutrosophic logic is connected with neutrosophic set and neutrosophic probability and statistics.

Mode And Implementation Of A Hybrid Control System For A 2-Mode Hybrid Electric Vehicle, Zhenhua Zhu
Graduate Theses, Dissertations, and Problem Reports
Automotive transportation consumes more than 71% of the world's total petroleum energy. The vehicle will have to use less because it will take less than 30 years to consume the rest of the proven conventional oil reservoir if the fuel consumption keeps the current trend. One of the methods to improve the vehicle efficiency is to develop Hybrid Electric Vehicle (HEV). An HEV combines an internal combustion engine (ICE) and electric motor(s) powered by batteries or capacitors to achieve better fuel economy. Among the HEVs, 2-Mode HEV combines an ICE and two electric motors with two planetary gear sets and …
