Respon Parking Bumper Bahan Komposit Polymeric Foam Diperkuat Serat Tandan Kosong Kelapa Sawit (TKKS) Akibat Beban Tekan Statik dan Dinamik (Simulasi Numerik)

Abstract

The investigation on the response of composite material parking bumper polymeric foam reinforced of oil palm empty fruit bunch fiber (EFB) has done by using static compressive load, free-fall impact experimental method, and numerical simulation. The experimentation was conducted to obtain the stress, strain, and impact force on the parking bumper structure with a trapezoidal-shaped on the upper side and on the inclined side of parking bumper. The specimen size and penetration diameter on the static compressive load have been adapted to the laboratory scale, whereas in free fall impact experimental load, specimen size and test rig dimension have been adjusted to the width of the wheels. The experimental data were provided for ANSYS software to calculate the response according to initial and boundary condition. The testing result showed that the stress and strain due to static compressive load, on the upper side are 1.04 MPa and 0.072, respectively; on the inclined side they reached up to 0.273 MPa and 0.003, respectively. The results of simulation showed that the stress and strain on th£ upper side are 0. 759 MPa, and 0.083, respectively; on the inclined side they reached up to 0.246 MPa and 0.026, respectively. The force and stress induced at the impacted area using free-fall impact apparatus on the upper side are 59.46 N and 0.0067 MPa, respectively; on the inclined side they reached up to 49.54 N and 0.00423 MPa, respectively. The stress and strain for numerical simulation on the upper side are 2.271 MPa and 0.0078, respectively; on the inclined side they reached up to 1.167 MP a and 0. 0040, respectively.
