Abstract

The thin-walled column structure or crash-box with metal material and consisting of multi-cell were found to be much more efficient in energy absorption than single-cell under axial impact loads. In this study, a numerical analysis was performed using the Abaqus finite element method for the cross-section differences in thin-walled column structures. The cross-section differences are compared to get a configuration that complies with the indicator parameters using the complex proportional assessment (COPRAS) method. The chosen cross-section configuration is further enhanced by creating elliptical holes with different diameter ratios. The results show that the thin-walled column structure with nine-cell cross-section accompanied by an elliptical hole ratio of 0.3 indicates the potential corresponding to the indicator parameters for the crashworthiness application.

Abstract

This paper's objective was to determine the dynamic response of a 19 passenger commuter aircraft windshield to impact angle variations. The phenomenon was performed using the finite element method, and the smoothed particle hydrodynamics (SPH) was chosen as a method for modeling bird material. The elastic-plastic polymethyl methacrylate (PMMA) material with the maximum principal strain failure criterion was used to model the windshield's dynamic response. The variation of the impact angle consists of 15°, 0°, -8°, and -15°, which are measured of the longitudinal axis of the aircraft. The simulation result showed that the impact angle that causes the windshield's dynamic response in the elastic, plastic deformation, and the greatest failure is the angle -15°. The upper end of the windshield (fixed) is the weakest part due to the stress concentration.

Abstract

This research studies influence of bird model on impact pressures during bird strike, namely Hugoniot and Stagnation pressure through initial modelling by numerical simulations using finite element method. Finite element simulation of bird strike have primarily modelled the bird as either a flat or hemispherically ended cylinder. The geometry is simulated with different L/D ratio, 1.4, 1.6, 1.8 and 2.0. Elastic-plastic hydrodynamic material model is used in simulation. Bird model simulation are using lagrangian method and initial velocities are 100, 200 and 300 m/s. Simulation results of hemispherically ended cylinder bird models show variation of L/D ratio provide Hugoniot pressure 10-19 times higher than stagnation pressure in L/D = 1.4, 8-18 times in L/D = 1.6, 9-17 times in L/D = 1.8 and 4-16 times in L/D = 2. The Hugoniot pressure shows a lower value at an L/D ratio of 1.6 compared to other ratios and the Stagnation pressure is higher at L/D ratio 2. As for cylindrical bird model show variation of L/D ratio provide Hugoniot pressure 35-38 times higher than stagnation pressure in L/D = 1.4, 30-47 times in L/D = 1.6, 31-52 times in L/D = 1.8 and 28-48 times in L/D = 2. The Hugoniot pressure shows a lower value at an L/D ratio of 1.4 and 1.6 compared to other ratios and the Stagnation pressure is higher at L/D ratio 2.

Abstract

Potensi perikanan Kabupaten Pangandaran cukup tinggi baik ikan laut maupun ikan tawar. Namun demikian  belum dapat dimanfaatkan secara optimal. Program pelatihan pembuatan ikan asap di Kabupaten Pangandaran bertujuan untuk memberdayakan Persatuan Istri Tentara (Persit) dalam meningkatkan keterampilan kewirausahaan dan pengolahan hasil perikanan. Pelatihan ini dilakukan dengan fokus pada pembuatan ikan asap sebagai produk olahan berbasis hasil laut yang bernilai tambah. Kegiatan ini dilaksanakan di Kampus Politeknik Kelautan dan Perikanan Pangandaran dengan mengajak peserta dari kalangan ibu-ibu Persit yang memiliki potensi besar untuk mengembangkan usaha kecil. Metode yang diterapkan meliputi sesi teori, demonstrasi praktis, dan pendampingan dalam produksi ikan asap. Evaluasi kegiatan dilakukan dengan memberikan kuisioner. Hasil evaluasi menunjukkan peningkatan pengetahuan dan keterampilan peserta sebesar lebih dari 90% serta terbentuknya kelompok usaha yang siap memasarkan produk ikan asap di pasar lokal. Program ini diharapkan dapat meningkatkan kemandirian ekonomi anggota Persit dan memberdayakan mereka dalam menghadapi tantangan ekonomi lokal.
