Finite element analysis and deployment of analytical hierarchical process for design of the structural framework for micro-actuators of vehicle crash box

Safety is one of the essential and vital factors in the case of the automobile industry. The vehicle has several safety features, like airbags, seat belts, antilock brakes, etc. The car's crash box is one of the crucial safety features that absorb the initial impact. The radiator, intercooler, fender, and hood are expensive parts of a car. A crash box can shield these components. A crash box can reduce the likelihood of the occupants dying or suffering significant injuries. The crash box absorbs kinetic energy from the moving car. This absorption lowers the possibility of occupant injuries and fatalities. Consequently, crash boxes are a crucial life-saving device used in cars. The crash box can be made of different (cross-section) shapes. The different shapes and materials of a crash box are investigated in this study. The study takes into account the square, rectangular, hexagonal, and pentagonal shapes. The configurations are simulated for the energy absorption study under impact load. Crash box analysis focuses on selecting the best material for the crash box and investigating its structural designs. The best material is chosen by applying Analytical Hierarchical Process (AHP).
