“…Pengaruh crush initiator juga sudah diteliti oleh Cho et al (Cho, et al, 2006) dengan mengetahui optimasi desain pada variasi ukuran hole-type dan dent-type sebagai crush initiator dimana diletakkan pada sudut tabung saat diberikan beban aksial. Eren et al (Eren, et al, 2009) juga sudah melakukan penelitian mengenai crush initiator tipe rib pada front side rail dengan menggunakan metode elemen hingga eksplisit dengan ANSYS/LS-DYNA.…”

“…Pada Gambar 9 , kondisi C terlihat mengalami initial buckling pada setiap tingkat crush initator khususnya tingkat 1 dan 2 secara serentak sehingga luas penampang pada daerah luasan yang terkena buckling akan mengalami penurunan yang berpengaruh pada penurunan gaya tumbukan maksimum seperti yang diteliti Cho et al (Cho, et al, 2006) dan Istiyanto et al …”

“…Often crash initiators were optimised (possible variables are depth, length, number and position of either beads or holes), e.g. [6]. Again, with the parameterisations chosen in these formulations, it is difficult to maintain a large design space and avoid geometrical clashes.…”

This paper presents a parametric shape optimisation approach using special parameterisation techniques for shape optimisation of structures with respect to crashworthiness. It is based on SFE CONCEPT which has the ability to modify shape using implicit parameterisation technique and adapt mesh to the new geometry through re-meshing. The success of shape optimisation depends on the type of parameterisation used. It is, therefore, important to choose a set of shape parameters which allow for larger range of shape configurations. However, the difficulty to deal with shape modifications grows with the increasing number of shape variables due to the arising geometrical conflicts. Hence, most shape optimisation studies use limited number of shape variables and also reduced parameter bounds which restrict large shape configurations. Here a new offset mapping technique is used to facilitate the definition of shape parameter conflicts without compromising the design space. To demonstrate this technique, a bumper beam shape optimisation is presented.

“…Some of the well cited works in this oblique impact are works of Borvik et al [5], Reyes et al [6][7][8] and Reid et al [9]. When the vehicle is subjected to an oblique loading, the frontal longitudinal collapses in a bending mode rather than axial crush [10], this causes to lower energy absorption capability of the frontal longitudinal.…”

This paper describes a computational investigation on the response of thin wall structures due to dynamic compression loading. In this paper, the tubes subjected for both direct and oblique loading. Several different cross-sectional structures have been studied to specify the best one. Initially the tubes were subjected to direct loading, and then the tubes were subjected to oblique loading. After that, the tubes were compared to obtain the cross section which fulfills the performance criteria. The selection was based on multi criteria decision making (MCDM) process. The performance parameters taken in this study are the specific energy absorbed by the tube for both direct and oblique, crush force efficiency and the ratio between the energy absorbed by direct and oblique loading. Trigger and foam filled are implemented to study their effects on the parameters used. The study used the magnesium alloy as a material to study potentially the possibility and ability of using the magnesium alloy in the energy absorber parts since the magnesium has lighter weight.
