Numerical and Experimental Investigation of the Effect of Different Orientation Angles on Crash Behavior of Composite Hat Shape Energy Absorber
Car body lightening and crashworthiness are two important objectives of car design. Due to their excellent performance, composite materials are extensively used in the car industries. In addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. Hat shape energy absorber is used in car’s doors for side impact protection. The aim of these numerical models and expe...
متن کاملExperimental Analysis of Crashworthiness Behavior of Energy Absorber Tubes Under 3D Oblique Load
Actual applications of the energy absorbers showed that actual loads are not applied in the form of pure axial compression, pure bending or pure torsion. In reality, an energy absorber component may be subjected to combined loading of compression, bending and torsion. A number of previous articles have investigated the behavior of energy absorbers under oblique loading. In such cases, the obliq...

متن کاملMulti-response Optimization of Grooved Circular Tubes Filled with Polyurethane Foam as Energy Absorber
The main objective of this research is to improvethe design and performance of the polyurethane foam-filled thin-walled aluminum grooved circular tubes using multi-response optimization (MRO) technique. The tubes are shaped with the inner and the outer circular grooves at different positions along the axis. For this aim, several numerical simulations using ABAQUS finite element explicit code ar...
متن کاملUsing of neural network and genetic algorithm in multiobjective optimization of collapsible energy absorbers
In this article,the multiobjective optimization of cylindrical aluminum tubes under axial impact load is presented. Absorbed energy and specific absorb energy are considered as objective functions while the mean crush load should not exceed allowable limit.The geometric dimentions of tubes including diameter and length of tube are selected as the design variables.The Non-dominated sorting Genet...
