| Summary: | 碩士 === 國立中正大學 === 機械工程所 === 95 === The purpose of the research is to develop a smart airbag structure. According to the investigation of NHTSA, in the accidents cause of airbag, there is a lot of proportion to happen on the out of position drivers. This is because airbags are designed in accordance with male in general. The airbag model that the research developed is to avoid this problem.
Use the experiment of head impact airbag to validate the airbag model. First use ANSYS-APDL create airbag model, use LS-DYNA let head drop model and airbag model put together and do simulation. Then compare the experiment result and simulation result.
Put the airbag model that validated before to the sled test model, do simulation in accordance with different dummy model. Use the Genetic Algorithms to change the radius of the airbag model and the tether which inside the airbag length, and the mass flow rate of airbag. To make the result of the sled test simulation be a good number, and get a smart airbag model.
