This study aimed to investigate the utility of the responses of the two child dummies (P1.5 and P3) that are placed in the rear seat, in identical forwardfacing child restraints during frontal Australian NCAP (ANCAP) tests. Dynamic responses of the two child dummies, vehicle crash parameters, and frontal dummy responses were extracted from the ANCAP report database for 35 frontal crash tests. L...

In a frontal vehicle crash, for a given crash velocity and given maximum vehicle crush, with a known restraint characteristic, what is the vehicle pulse, subject to lower and upper bound constraints, that produces the lowest peak occupant deceleration? A solution procedure using numerical optimization is proposed. The pulse is discretized in the vehicle crush domain. The optimization search is ...

Cardiac myxomas are benign tumors composed of sparse stellate cells in an extensive mucoid stroma. The surface of these tumors is often friable and gelatinous. Their intracardiac location makes embolization a constant threat. We report a patient who had diffuse systemic embolization of a left atrial myxoma coincident with a low-velocity frontal motor vehicle crash.

The paper describes the experimental validation of biomechanical response Hybrid III 50th Percentile Male Pedestrian Dummy (JASTI, Tokyo, Japan) at low impact velocity (up to 2.2 m/s) in comparison with that human probands. is based on previous research was focused tram-pedestrian crash tests using same dummy. biofidelity dummy analyzed two collision scenarios: anteroposterior (chest impact) an...

This paper built the 100% frontal crash model of minibus, 8 thickness components which have obvious effect on vehicle performance were selected as design variables, and choose appropriate evaluation index responses. Use DOE experimental method to get 70 set training data Kriging approximate based data. The is optimized by PSO algorithm, in scheme, amax m has decreased 7.6% 0.87%, D1, D2 D3 7.7%...

Objective: Frontal crash accidents remain a significant factor in causing the preventable injury and fatality for child occupants aged 3 China. Despite increased public awareness utilization of restraint system (CRS), inappropriate installations still exist lead to potential result injuries head, thorax abdomen regions occupants, especially when it comes enhanced (ECRS) with top tether. The cur...

The study is focused on the dynamic response of head and thoracic area an anthropomorphic test device (ATD) during low-impact collisions with a tram. Two collision scenarios were analyzed: frontal impact (a chest as primary contact area) side thigh area). measurements used pedestrian dummy (Hybrid III 50th percentile male dummy, Jasti Co., ltd., Tokyo, Japan) unique pendulum testing machine (im...

Traffic safety technologies revolve around two principle ideas; crash avoidance and injury mitigation for inevitable crashes. The development of relevant vehicle mitigating should consider the interaction those technologies, ensuring that crashes can be adequately managed by occupant vulnerable road user (VRU) protection systems. A step towards is accurate description expected remaining when cr...

Despite considerable improvements in frontal impact crashworthiness, frontal crashes still account for a major number of front seat occupant fatalities in Great Britain. This study attempted to determine the remaining potential for further fatality reduction with passive safety improvements in frontal crashes. No evidence was found to support an increase in crash test speeds. Instead, assessmen...

The goal of the study was to conduct a preliminary analysis kinematics tram-pedestrian collision in case side impact. A T6A5-type tram, traveling at speed 10 km/h, used for crash and reconstruction collision. pedestrian response analyzed using crash-test dummy. For purpose this study, postimpact dummy movement approximated by motion its center mass (COM) only translation frontal plane (along ho...
