| Summary: | 博士 === 國立中央大學 === 機械工程學系 === 101 === The medical treatment cost of occupant deaths and injuries caused by motor vehicle crashes is the major concern of economic burdens. The purpose of this paper was to develop an integrated methodology which links occupant injury risk of motor vehicle crash and medical treatment cost. A modified coupled simulation model was proposed to faster and more accurate estimate the occupant biomechanical response during the crash in the different accident geometry. And various injure sacle of specific body region and severities could be estimated by the real world crash database in Taiwan. Then integrated methodology of medical cost prediction was developed to link the simulation of injury in the different body region and severities. This paper in-depth studied the influence of driver’s body injury severity to medical treatment cost in car-to-car crashes for changes in vehicle mass, impact closing speed from 30km/h to 70km/h, and airbag status. The integrated methodology can be used to recover the insufficient information of real world especially the velocity change during the crash event. This paper proposed an innovated method to assess the safety of vehicle.
This paper was also designed to study how drivers (29 men, 29 women) respond to a risky situation. Sex did not influence the driver’ responses. As expected, for shorter cut-in time gaps, the steering wheel angles were smaller, the speeds were lower, and the variations in the steering wheel angle and speed were larger. The response patterns characterised by the speed-associated measurements can coonect with the modified coupled simulation model to estimate more accurate medical treat cost prediction in the car accidence. Hence, This paper has derived how the integrated methodology links crash injury cast and medical treatment cost was developed.
