Multi-objective design optimization for crash safety of a vehicle with a viscoelastic body and wide tapered multi-cell energy absorber using DOE method
Due to the extensive use of cars and progresses in the vehicular industries, it has become necessary to design vehicles with higher levels of safety standards. Development of the computer aided design and analysis techniques has enabled employing well-developed commercial finite-element-based crash simulation computer codes, in recent years. The present study is an attempt to optimize behavi...
متن کاملIntelligent Methods for Car Deformation Modeling and Crash Speed Estimation
Car body deformation modeling plays a very important role in crash accident analyses, as well as in safe car body design. The determination of the energy absorbed by the deformation and the corresponding Energy Equivalent Speed can be of key importance, however their precise determination is a very difficult task. Although, using the results of crash tests, intelligent and soft methods offer an...
