Optimal crashworthiness design of thin-walled circular tubes with triggering holes

By applying the moving least square surface fitting technique and genetic algorithm optimization technology,a complete structural optimization design technique for crashworthiness was proposed and the corresponding program codes were developed to realize the typical aircraft structure crashworthiness optimization design.Thin-walled cylindrical aluminum tubes with triggering holes were designed and proven to have high efficiency in energy absorption.The results show that this thin-walled cylindrical structure has a high energy absorption capacity and it is easy in application.
