Crash test for the Copenhagen problem
Physical Review E, 2004The Copenhagen problem is a simple model in celestial mechanics. It serves to investigate the behavior of a small body under the gravitational influence of two equally heavy primary bodies. We present a partition of orbits into classes of various kinds of regular motion, chaotic motion, escape and crash.

For the homologation of busses and coaches, crash tests of entire vehicles are not required. Overturn tests are simulated on PC and the test of single components such as seats and their structure are carried out on the test bed. For years now, the Institute for Automotive Engineering at the Trier University of Applied Sciences has been engaged in the ...

Automobile crash simulation with the first pregnant crash test dummy
American Journal of Obstetrics and Gynecology, 1996Our goal was to develop a pregnancy insert for the Hybrid III (First Technology, Farmington, Mich.) crash dummy allowing evaluation of the effects of various restraint conditions on energy transmission to both the fetal and maternal compartments.A pregnancy insert with an elasticized vinyl uterine shell, simulated silicon amniotic fluid, and a 28-week ...

Crash pulse recorder—validation in full scale crash tests
Accident Analysis & Prevention, 1995Estimation of the accident severity is a fundamental requirement in accident reconstruction and analysis. Accident severity can be measured in many different ways, but in frontal collisions change of velocity, energy equivalent speed or equivalent barrier speed are frequently used parameters.

Comparison of roadside and vehicle crash test injury criteria in frontal crash tests
International Journal of Vehicle Safety, 2008The flail space model is widely used to assess occupant injury risk potential in full-scale crash tests of roadside safety hardware, e.g. guardrail. A fundamental assumption of this model is that the occupant is unbelted and not airbag restrained. In the early 1980s, these were valid assumptions in the US: cars were not airbag equipped and belt usage ...

Science, 1998
Simulations of the behavior of complex structures--the crash of a car, for instance--can only succeed if the detailed response of materials to stress can be accounted for. In his research commentary, Gumbsch discusses results reported in the same issue by Zhou et al .

Ensuring safety leads to various aspects ranging from preventing electrical threats to coping with human mistakes. Up to now, this monograph focused on developing different methods for collision avoidance, detection, and reaction, i.e. to equip the robot with reactive motion control capabilities to appropriately react to environmental changes and ...

Nature, 1999
Some populations of animals undergo dramatic cycles in which the numbers vary considerably, and the causes of such cycles have long been debated. Two long-term, large-scale experiments on red grouse in Scotland and voles in Finland conclude that the respective agents of population crashes in these cases are a parasitic nematode and predator pressure.

Numerical Simulation of Motorcycles Crash Test
2004Recently has been introduced the ISO 13232 standard in order to granter security in crash. Objective of this communication is to demonstrate how the multibody model can be used to make a first screening of the projects before verification on the field.
