| Summary: | 碩士 === 大葉大學 === 車輛工程學系碩士班 === 94 === The number of cars is increasing, leading to more traffic accidents. Traffic accidents have become one of the leading causes of death in modern times. Car safety has become the most important issue in automobile development. To confirm vehicle occupant safety, most countries issue safety standards and regulations to which vehicles must conform. For the side impact test regulation, the regulations produced by each country have a lot of difference in test methods, causing confusing data after tests. In order to reduce the difference between side impact regulations, International Harmonized Research Activities positively harmonized contents of side impact regulations to make it globalized. This study investigates the development and validation dummy, MDB and side-impact crash test FEM model for studying interaction. Based on the FMVSS 214 and ECE R95 regulation, the numerical crash test model was developed to simulate a side impact accident. The crash simulations were conducted using the LS-DYNA finite element code. The dynamic response of the human body to crashes is discussed herein. Additionally, the injuries of occupants were measured. The simulated models obtained could help evaluate vehicle crash safety and guide the future development of safety technologies. According to the injury of occupant, the assessment of the severity levels of side impact regulations was performed, except for using the difference of these two side impact regulations to realize the way to legislate the standard. Through all these analytical results, the references will be provided and harmonized side impact regulation will be understood clearly. At last, the result of this thesis also gives some suggestions to legislate our side impact regulation.
