The Australian Centre for Robotic Vision is an unincorporated collaborative venture with funding of $m over seven years to pursue an ambitious research agenda tackling the critical and complex challenge of applying robotics in the real world.
Based on the European New Car Assessment Program, which offers rigorous testing conditions, this study developed a numerical model for the computer simulation of crash analysis and analyzed two crash situations: a high-speed vehicle crashing into a wall and a high-speed test vehicle crashing into a static vehicle.
The Simulation model was constructed using the superior functions of the Patran Author: Cherng Shing Lin, Kuo Da Chou, Chia Chun Yu.
The Crew Return Vehicle (CRV), sometimes referred to as the Assured Crew Return Vehicle (ACRV), was a proposed dedicated lifeboat or escape module for the International Space Station (ISS). A number of different vehicles and designs were considered over two decades – with several flying as developmental test prototypes – but none became operational.

The simulation of road vehicle flow is thus important in the analysis of the dynamic interaction between road vehicles and bridges. Rather simple patterns of road vehicle flow have been assumed in most vehicle-bridge coupled dynamic analyses [ 79, 81, 82 ] in which either one or several vehicles are distributed on the bridge in an assumed Cited by: 1.

The dynamic transient response of a vehicle during rapid variations in driving torque is strongly influenced by the drive-line. An accurate numerical analysis to evaluate the vehicle performance in maneuvers which mainly interest longitudinal dynamics - such as rapid variations of the throttle or traction efforts - requires the development of a model able to simulate the dynamic behavior of Cited by: 3.
Hence, detailed knowledge of the flow field around corner vanes is essential to improved fuel efficiency and reduced dirt contamination on the vehicle body surface. In this study, three-dimensional flow characteristics around a corner vane attached to a truck cab were computed for steady, incompressible, and high-speed viscous flow, adopting a Cited by: 2.

Comparison of numerical flow field. The lifting body is an aircraft configuration where the body itself produces is related to flying wing which is a wing without a conventional fuselage. A lifting body is a fuselage that generates lift without the shape of a typical thin and flat wing structure.
A flying wing seeks to maximize cruise efficiency at subsonic speeds by eliminating non-lifting surfaces. BACKGROUND OF THE INVENTION 1. Field of the Invention. The invention relates to space transportation and exploration vehicles and more particularly, to a space vehicle which may be employed to reliably and safely return crew members from an earth orbiting vehicle, such as a space station or the like, to the earth with a minimum of cost and on-orbit preparation.
