Development Of Attachments For The Quanser Qube, Diane Peters, Aaron Joseph Michael Jones
Development Of Attachments For The Quanser Qube, Diane Peters, Aaron Joseph Michael Jones
Mechanical Engineering Presentations And Conference Materials
The Quanser Qube is an integrated servomotor lab hardware platform [1], shown in Figure 1. This platform includes not only the direct-drive brushed DC motor, but also two encoders as well as the data acquisition system. One encoder is used to measure the rotation of the DC motor’s shaft itself. It is supplied with two standard items, an inertia disk and an inverted pendulum. The inertia disk is a small aluminum part, which mounts to the equipment using magnets. The inverted pendulum also mounts to the equipment with magnets, with an encoder that plugs into the equipment to provide an …
Effect Of Neural Network On Reduction Of Noise For Edge Detection, Diane Peters, Enqi Zhang, James Z. Zhang
Effect Of Neural Network On Reduction Of Noise For Edge Detection, Diane Peters, Enqi Zhang, James Z. Zhang
Mechanical Engineering Presentations And Conference Materials
Processing photographic images is important in many applications, among them the development of automated driver assistance systems (ADAS) and autonomous vehicles. Many techniques are used for processing images, including neural networks, other types of machine learning, and edge detection. One common issue with processing these photos is the presence of noise, whether caused by the camera itself or by physical conditions (e.g., weather conditions or dirt on road signs). In this paper, a neural network is used for noise reduction to improve edge detection results and tested with two kinds of noise, Gaussian and salt & pepper noise, and three …

The Autodrive Challenge: Autonomous Vehicles Education And Training Issues, Diane Peters, Jennifer Bastiaan, Juan R. Pimentel, Mehrdad Zadeh
Mechanical Engineering Presentations And Conference Materials
Automotive companies are focusing significant research and development efforts on autonomous vehicles. As they do so, they recognize the need for a large, well-trained workforce that is equipped to conduct these research and development projects, particularly in light of the projected shortages of STEM professionals in the United States. Some of these companies have found various ways to engage with professional societies and with universities to encourage the development of this workforce, and to promote themselves to STEM students while they are still in school. One such effort is the SAE / GM AutoDrive ChallengeTM, a new collegiate competition organized …
Dynamic Analysis Of Vehicle Performance For Changes To Rear Axle Housing, Diane Peters, Yaomin Dong, Vimal Patel
Dynamic Analysis Of Vehicle Performance For Changes To Rear Axle Housing, Diane Peters, Yaomin Dong, Vimal Patel
Mechanical Engineering Presentations And Conference Materials
This paper explores the performance improvements of a 2013 Ford Mustang Shelby GT500 resulting from changes to the rear axle housing. In previous work, described in [1, 2], the rear axle housing was optimized in order to minimize its weight. It was expected that the decrease in weight would lead to improved fuel economy; in this work, the vehicle was simulated for the EPA highway drive cycle (HWFET) both before and after the optimization of the housing, in order to quantify the changes in fuel economy. It was found that the optimization of the housing did produce a modest improvement …
Crash Safety In The Introductory Physics Lab, Daniel Ludwigsen, Janet Brelin-Fornari, Joseph Neal
Crash Safety In The Introductory Physics Lab, Daniel Ludwigsen, Janet Brelin-Fornari, Joseph Neal
Mechanical Engineering Presentations And Conference Materials
Crash Safety in the Introductory Physics Lab Abstract In the field of vehicle occupant protection and crash safety, the Deceleration Sled offers researchers a controlled, repeatable, and relatively cost-effective means to test interior parts such as safety restraint systems. The sled can accelerate a 2000 lb payload to achieve a speed of 40 mph before a hydraulically controlled deceleration models the deformation of the vehicle structure during a crash. Understanding the dynamics of the sled and interpreting test results incorporates many of the core concepts of a first course in introductory physics. This application of physics principles is the inspiration …
Sensitivity Analysis Of Hill Muscle Parameters, Janet Brelin-Fornari, Paras Shah, Mohamed El-Sayed
Sensitivity Analysis Of Hill Muscle Parameters, Janet Brelin-Fornari, Paras Shah, Mohamed El-Sayed
Mechanical Engineering Presentations And Conference Materials
A computational, rigid body model of a 50th percentile male head and neck utilizing 15 Hill Muscle pairs is used to study the sensitivity of Hill Muscle Model parameters. A 15g linear acceleration is applied within the transverse plane at the lowest vertebral level of the neck (T1). The resultant linear acceleration of the head is analyzed. In response is minimally affected. The peak accelerations did change, and in the case of varying muscle activation, the peak acceleration changed significantly, 36%. Each of the other parameter variations affected the peak acceleration of the head by less than 5%. Overall, …
An Under-Hand Steering Wheel Grasp Produces Significant Risk To The Upper Extremity During Airbag Deployment, Patrick J. Atkinson, Prem Hariharan, Shresta Mari-Gowda, Paul Telehowski, Sidney Martin, Jack Van Hoof, Cynthia Bir, Theresa Atkinson
An Under-Hand Steering Wheel Grasp Produces Significant Risk To The Upper Extremity During Airbag Deployment, Patrick J. Atkinson, Prem Hariharan, Shresta Mari-Gowda, Paul Telehowski, Sidney Martin, Jack Van Hoof, Cynthia Bir, Theresa Atkinson
Mechanical Engineering Presentations And Conference Materials
Recent laboratory investigations suggest that a deploying airbag may fracture the forearm. These studies positioned the arm in an overhand grasp placing the forearm over the airbag module. However, there is little published data on how drivers grip the steering wheel and the general proximity of the upper extremity to the airbag module. The objective of the current study was to identify 'real world' upper extremity positions and to correlate these with accident and experimental data. A survey of the National Automotive Sampling System (NASS) for the years 1995-99 revealed an increase in the number of forearm fractures due to …
A Study Of Muscle Activation In A Mathematical Model Of The Human Head And Neck, Janet Brelin-Fornari, A. Arabyan
A Study Of Muscle Activation In A Mathematical Model Of The Human Head And Neck, Janet Brelin-Fornari, A. Arabyan
Mechanical Engineering Presentations And Conference Materials
A model of the human head and neck that incorporates active and passive muscles is utilized in the analysis of non-impact loading in high “g” environments. The active muscles have the capability to be activated partially and in different combinations.The model is implemented in MADYMO using lumped parameters and Hill muscles. A comparison of simulation results with experimental data, generated by the Naval Biodynamics Laboratory (NBDL) for neck flexion and rebound, shows excellent agreement for a 15g impulsive load.
