SAE Vehicle Electrification: February 11, 2014

2014-02-11
Inside the cell walls The high cost of lithium-ion batteries is a prison that has largely kept electric vehicles off the street; the keys to their release are more effective—but not more expensive—cell chemistries.

Auto Brand

2014-01-03
The car - once everybody's dream and a key status symbol in most countries and cultures - has been extensively questioned in the last decades and in the last few years particularly. Urbanization, traffic congestion, pollution problems, heavy reliance on scarce oil supplies, safety issues and ever-growing competition, have all provided significant business challenges for the automotive industry. Many car manufacturers have had to fundamentally rethink their design, brand and marketing strategies to thrive in a savvy, consumer-led culture, and markets that are becoming increasingly restrictive in size and opportunity.

Test Method for Catalytic Carbon Brake Disk Oxidation

2013-12-04
WIP
AS6289
The scope of the test method is to provide stakeholders including fluid manufacturers, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This test is designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions.

Transport Revolutions

2008-01-01
This book sets out the challenges that will soon threaten modern society's dependence on low-cost transport in light of the problems posed by oil supply and climate change. It proposes organizational and technical innovations that could ensure effective, secure movement of people and goods in ways that minimize environmental impacts and make the best use of renewable sources of energy. The authors conclude that transport in the first half of the 21st century will feature at least two revolutions. One will involve the use of electric drives rather than internal combustion engines. The other will involve powering these drives directly from the electric grid rather than from on-board fuel. The authors also address revolutions in marine transport and aviation and analyze the politics and business of transport and how these will undergo profound change in the decades ahead.

Performance based packaging standard for lithium batteries as cargo on aircraft

2016-03-18
WIP
AS6413
This standard is intended to demonstrate and document the control of the potential hazards from lithium cells or batteries (UN 3090 and 3480) when transported as cargo on aircraft. [still need to identify if we are addressing global (external fire) or local (battery internal failures)] This standard addresses the need to control the hazards which might arise from a failure from an individual cell by containing the hazards within the package. This specific hazards addressed within this standard are: • Uncontrolled fire • Rapid overpressure pulse within compartment

A Driving Simulator Using Microprocessors

1988-03-01
871156
An inexpensive driving simulation system with sufficient fidelity has been developed. The system produces motion cues of four degrees of freedom, visual and auditory cues, and control feel on the steering wheel. This paper describes the features of this newly developed system and gives examples that demonstrate its effectiveness. The motion cues provided in this system are yaw, heave, and lateral and fore/aft accelerations. The lateral and fore/aft accelerations are simulated by tilting the simulator compartment. A computer-processed road image is given through a CRT monitor. The restoring torque of the steering wheel is produced by an electrical servosystem via a coil spring. Cruising sound is given in order to improve speed perception. Since the system uses digital computers, the vehicle characteristics are altered easily by merely rewriting the software. This enables us to simulate special vehicle dynamics such as front & rear wheel steering.

A Study on the Performance of Guideway Bus Steering Control System

1988-03-01
871231
In this paper a computer simulation study on the effects of steering parameters on lateral dynamics of the guideway bus to contribute to a development practice of designing optimum steering control system are dealt with. A stability limit of vehicle lateral motion is analyzed and an emphasis is laid on the effects of moment of inertia of a conventional steering wheel and lateral elasticity of the guide rail which have proven to reduce the critical vehicle speed. It is pointed out conclusively that a normal bus equipped with additional simple guidance equipments can be guided smoothly on a simple guideway at adequately high vehicle speed.

Tire/Road Interface Airborne Noise Characteristics Generation

1999-05-17
1999-01-1731
In recent years there has been much interest in problems involving the noise prediction and reduction inside and outside the vehicle. Tire/road exterior noise has been considered to be the major vehicle exterior noise source. However, this paper describes an investigation into the characteristics of the air pumping noise mechanism in terms of source locations and directionality. Some rubber tire/road air pumping noise measurements are presented, whereas some predicted results are computed based on the boundary element method (BEM) to display some parameters which are found to be difficult to be obtained experimentally.
