“…Balls in DEM were utilized to simulate the sandy soil, while meshes in FEM were employed to create the suction anchors. The deformation of the suction anchors in the centrifuge tests was small relative to the displacement, satisfying the criteria for employing the one-way transient coupled DEM-FEM simulations [24,25]. Similar to previous investigations [14,19,26], the one-way transient coupling method was employed in simulations.…”

The microscale mechanisms underlying the suction anchor–sandy soil interaction under slidable pulling actions of mooring lines remain poorly understood. This technical note addresses this knowledge gap by investigating the suction anchor–sandy soil interaction from micro to macro, with a particular emphasis on the effect of interface friction. The discrete element method (DEM) was utilized to simulate the sandy soil, while the finite element method (FEM) was employed to model the suction anchors. The peak pulling forces in numerical simulations were verified by centrifuge test results. The research findings highlight the significant influence of interface friction on the pulling force–displacement curves, as it affects the patterns of suction anchor–sandy soil interactions. Furthermore, clear relationships were established between the magnitude of interface friction, rotation angle, and pullout displacement of suction anchors. By examining the macro-to-micro behaviors of suction anchor–sandy soil interactions, this study concludes with a comprehensive understanding of failure patterns and their key characteristics under different interface friction conditions. The findings proved that the interface friction not only influences the anti-pullout capacity but also changes the failure patterns of suction anchor–soil interactions in marine engineering.

“…Metode Fenite Element Analysis (FEA) merupakan sebuah metode yang digunakan untuk menganalisis tegangan dan parameter lainnya [10]. Fenite Element Analysis (FEA) memiliki kelebihan diantaranya untuk mengoptimalkan desian, melakukan perhitungan secara teoritis, memprediksi kekuatan sebuah material [11], [12] dan meverifikasi gaya pembebanan dengan analisis regresi [13]. Pemilihan material bertujuan untuk mencari material yang mempunyai sifat dengan persyaratan yang dibutuhkan dalam proses desain [14].…”

Aktivitas pemindahan barang secara manual sering kita jumpai diberbagai tempat kerja. Pada penggunaan troli barang ini, banyak karyawan yang mengalami keluhan seperti sakit punggung, keseleo pada punggung bagian bawah, bahu dan tungkai sehingga mengakibatkan cedera dan kehilangan produktivitas. Penelitian ini bertujuan merancang ulang rangka troli pengangkut barang Laboratorium Manufaktur ITNY menggunakan material aluminium 6061 guna meminimalisir permasalahan dalam hal perawatan dan pengecetan ulang yang dilakukan secara teratur dan berkala. Metode yang digunakan adalah fenite element method, dengan variasi pembebabanan 10000N, 20000N, 30000N, 40000N, 50000N, 60000N, 70000N, 80000N dan 90000N. Hasil simulasi troli menunjukkan bahwa terjadi kenaikan nilai von mises stress maximum terjadi pada pembebabanan 50000N ke 60000N sebesar 81,43 MPa. Kenaikan deformasi yang paling signifikan terjadi pada pembebaban 50000N ke 60000N sebesar 2,8527mm. Penurunan nilai angka keamanan yang paling signifikan terjadi pada simulasi pembebanan dari 10000N ke 20000N sebesar 3,806. Desain troli yang diusulkan dengan material bahan aluminium 6061 dapat menahan beban hingga 30000N

“…The study concluded that the decreased thickness of the moldboard frame did not lead to undue stresses, and the observed strains closely matched the simulated data. Kesner et al [25] established a computational model of a tillage machine to analyze these loads. The result showed that the experimental stress measurements aligned well with the simulation data obtained from the model.…”

Stress measurements play a crucial role in safety analyses of transplanting devices. Strain gauges for stress measurements during field tests can be expensive and time-consuming. The aim of this study was to investigate the stress on the transplanting device of a cam-type semiautomatic vegetable transplanter using a simulation method. A three-dimensional simulation model was established, considering the dimensions and material properties of the transplanting device. The stress distribution and maximum stress values were obtained through simulations. The maximum stress values at 15 points within the transplanting device determined via the simulation were compared with the experimental stress data to verify the stress simulation model. The results show that the maximum stress obtained from the simulation correlated with that of the measured results, although differences were observed at different locations, particularly at strain gauge positions 11 and 13. Based on the simulation results, the maximum stress occurs at the upper link of the cam-type transplanting device, reaching a magnitude of 201.21 MPa, and the static safety factor is 1.04.
