Motorcycle road traffic accidents represent a big concern, as vulnerable users account for more than half of all deaths worldwide. The estimation the influential factors associated with increase injury severity motorcyclists involved in accident is extreme importance it provides necessary basis development an appropriate and targeted sustainable prevention plan improving safety. This study adopted decision tree, ordered logistic regression (LR), random forest (RF), gradient boosting,...
Different formulations based on multibody dynamics are shown to be suitable for the development of a methodology impact simulation and crashworthiness design railway vehicles. The proposed comprises different computer-aided tools increasing complexity accuracy which can used with greater advantage efficiency in stages stock. In general, methods associated dynamic presented this paper require information obtained from numerical or experimental crush tests specific structural components,...
Abstract The development of strategies for the passive safety protection road vehicles, such as restraint systems, only focus on a part vehicle but still require complete model to simulate realistic scenarios. Unfortunately models vehicles are not available by car manufacturers this purpose. Here multibody vehicle, including occupant models, is presented application design side impact protection. structure represented system rigid bodies connected kinematic joints and plastic hinges. hinges...
This paper describes a methodology for the sensitivity analysis and optimization of planar constrained mechanical systems. Direct differentiation methods finite difference techniques have been used in design calculations. The process is developed within framework mathematical programming techniques. equations were constructed symbolically, subsequently integrated dynamic motion solved simultaneously. Some examples are to demonstrate use including crashworthiness problem, where plastic hinge...
The aim of this study was to determine the risk factors associated with increase injury severity powered two wheelers (PTW) riders when involved in a road accident Portugal.A retrospective analysis 37769 PTW accidents that occurred Portugal between 2010 and 2015 performed. Injury classified into 3 levels: minor injury, severe fatal injury. An ordered logistic regression applied identify potential can affect severity.The following chances more injuries: motorcycle category, rest days, 20 h...
Pedestrians represent about 20% of the overall fatalities in Europe's road traffic accidents, as well Portugal. An in-depth investigation, accident reconstruction, is mandatory order to analyze with care fundamental aspects an accident. Detailed information injuries and injury causation mechanisms are great use for it. Accident reconstruction computational techniques using pedestrian biomechanical models used evaluate conditions that lead major injuries, such vehicle's speed impact location....
