Multi-objective Optimization of Crashworthiness of Cylindrical Tubes as Energy Absorbers

In this article, the multi-objective optimization of cylindrical aluminum tubes under axial impact load is presented.The absorbed energy and the specific absorbed energy (SEA) are considered as objective functions while the maximum crush load should not exceed allowable limit. The geometric dimensions of tubes including diameter, length and thickness are chosen as design variables. The Non-domi...

Optimization foam filled thin-walled structures for the crashworthiness capability: Review

In automotive industry, foam-filled structures have aroused increasing interest because of lightweight and capacity of energy absorption. Two types of foam filled thin walled structures such as the uniform foam filled (UF) and the functionally graded foam (FGF). To improve crashworthiness performance, FGF are used to fill structures, unlike existing uniform foam materials. In addition, by seeki...

Multi-objective Crashworthiness Optimization of the Aluminum Foam-filled Tubes

In order to reduce both the weight of vehicles and the damage of occupants in a crash event simultaneously, it is necessary to perform a multi-objective optimization of the automotive energy absorbing components. In this paper, axial impact crushing behavior of the aluminum foam-filled thin-walled tubes are studied by the finite element method using commercial software ABAQUS. Comparison of the...

Parameter-based topology optimization for crashworthiness structures

Abstract Topology optimization methods like the homogenization method are very efficient for statically and dynamically loaded structures, but the use of these methods for the topology optimization of crashworthiness structures runs into a lot of problems. Especially in structural contact problems, the optimization functions are not smooth and the use of local sensitivity information is not suc...
