An advanced crash test dummy, THOR, is proposed in the test protocol for injury risk assessment instead of the standard frontal impact dummy Hybrid III (H-III). An integrated vehicle finite element model with H-III, THOR and the GHBMC 50th male models is employed to compare the kinematics and injury differences. In this study, we evaluated the occupant response in the new frontal OMDB test using GHBMC models to quantify and qualify the potential injury pattern and risk in this type of crash. The vehicle model was validated with both a full frontal 35 mph rigid barrier test and the very first frontal OMDB test with the H-III 50th %ile male dummies is conducted. The differences in the measured responses of the H-III and THOR from simulations and tests, and the simulated responses of the GHBMC model, were compared. The additional tissue-level injuries predicted by the GMBMC model, which are beyond the capability of the H-III and THOR dummies, showed the potential injury pattern and risk of occupants in the OMDB test.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"10 1","pages":"301"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66693552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Logistic regression analyses were conducted to evaluate the factors affecting the injury risk for children aged 4-18. Results showed that seatbelt was the most common form of restraint for children older than four years of age seated in the rear seat. Children 8-12 years of age were at the highest risk of significant injury among children 4-18 years old. The risks of significant injury by body regions varied among children 4-18 years old due to the differences in anthropometry. Children 4-8 years of age appeared to be at increased risk of injury from using seat belts, whereas children 9-18 years of age experienced protective effects of using seat belts.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"10 1","pages":"288-300"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2018.097721","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66693933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The implementation of airbags has been shown to offer passenger safety in a collision. However, premature deployment and malfunction of airbag has resulted in fatalities and injuries to drivers and front seat passengers. In this study, a magneto-rheological (MR) damper is used as a replacement of airbag in vehicles to serve as a protective system. MR damper is a smart damping device which can be programmed to dynamically absorb shocks and high impact force when used in application such as passenger cars. In this paper, G-force profile of the airbag vehicle crashing system is compared with the G-force profile obtained from the MR damper vehicle crashing system. Subsequently, for this purpose MR damper characteristics are designed and Fuzzy Logic Controller (FLC) and Proportional Integral Derivative (PID) controller are proposed for MR damper current control. Simulation results proved that fuzzy based MR damper system yields better results compared to PID based MR damper system and airbag vehicle crashing system.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"338-351"},"PeriodicalIF":0.0,"publicationDate":"2017-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2017.087165","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46307865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The complete model was verified by comparing to available cadaveric test data. Then it was used to simulate collisions of midsize car/SUV-paediatric pedestrian at different collision speeds, in order to study the effects of collision speed, and vehicle type on kinematic/biomechanical responses of paediatric chest and abdomen, and to predict the injuries of bones and internal organs according to compression/viscous criterion and strain. Simulation results showed that the number of rib fractures increased with the increase of collision speed in collision simulations of midsize car-paediatric pedestrian, but no rib fracture appeared in simulations of SUV-paediatric pedestrian impact. Maximum values of chest/abdomen/thigh impact forces, maximum deformation/VCmax of paediatric chest and abdomen, and maximum first principal strain of internal organs were proportional to collision speed. Predicted paediatric chest and abdominal injuries, obtained from the midsize car-pedestrian simulations, were found to be consistent when compression/viscous criterion and first principal strain were used as a yardstick for injury assessment. Additionally, compression/viscous criteria had some limitations on the prediction of rib fracture in SUV-pedestrian collision simulations.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"279-297"},"PeriodicalIF":0.0,"publicationDate":"2017-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47173005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
