Abstract

Proses pengujian bending tiang baja di PT Steel Pipe Industry of Indonesia (PT SPINDO) Unit II masih menggunakan block clamp eksisting yang memiliki keterbatasan dalam menjepit beberapa variasi diameter tiang sehingga diperlukan penggantian block clamp pada setiap ukuran tiang. Kondisi tersebut menyebabkan proses setup menjadi kurang efisien serta berpotensi mengurangi kestabilan penjepitan selama pengujian. Oleh karena itu, penelitian ini bertujuan merancang v-groove block clamp yang mampu menjepit tiang baja berdiameter 2½”, 3”, dan 4” menggunakan satu desain block clamp. Perancangan dilakukan menggunakan perangkat lunak SolidWorks, sedangkan analisis kekuatan struktur dilakukan menggunakan ANSYS Static Structural dengan metode Finite Element Analysis (FEA). Material yang digunakan adalah S45C dengan pembebanan sebesar 1.176,8 N yang disesuaikan dengan kondisi aktual mesin uji bending. Parameter yang dianalisis meliputi equivalent von mises stress, total deformation, dan safety factor untuk mengevaluasi performa struktural v-groove block clamp dibandingkan dengan block clamp eksisting. Hasil simulasi menunjukkan bahwa v-groove block clamp menghasilkan nilai equivalent von mises stress maksimum sebesar 276,41 MPa, lebih rendah dibandingkan block clamp eksisting sebesar 354,30 MPa. Nilai safety factor minimum meningkat dari 1,419 menjadi 1,786, sedangkan total deformation maksimum meningkat dari 0,12238 mm menjadi 0,19347 mm. Meskipun deformasi meningkat, nilainya masih tergolong kecil sehingga tidak memengaruhi fungsi penjepitan. Berdasarkan hasil tersebut, v-groove block clamp mampu memberikan distribusi tegangan yang lebih baik dan tingkat keamanan yang lebih tinggi dibandingkan block clamp eksisting, sehingga layak digunakan sebagai alternatif sistem penjepit pada mesin uji bending tiang baja.

The steel pole bending test process at PT Steel Pipe Industry of Indonesia (PT SPINDO) Unit II currently utilizes an existing block clamp that is unable to accommodate multiple pole diameters without replacing the clamp, resulting in reduced setup efficiency and less stable clamping during testing. Therefore, this study aims to design a V-Groove Block Clamp capable of clamping 2½-inch, 3-inch, and 4-inch diameter steel poles using a single clamp design. The proposed design was developed using SolidWorks, while structural analysis was conducted using ANSYS Static Structural based on the Finite Element Analysis (FEA) method. The block clamp was modeled using S45C steel and subjected to an applied load of 1,176.8 N, representing the actual loading condition of the steel pole bending test machine. The evaluated parameters included Equivalent (Von Mises) Stress, Total Deformation, and Safety Factor to assess the structural performance of the proposed V-Groove Block Clamp in comparison with the existing block clamp. The simulation results indicate that the proposed V-Groove Block Clamp produces a maximum Equivalent (Von Mises) Stress of 276.41 MPa, which is lower than the 354.30 MPa obtained by the existing block clamp. The minimum Safety Factor increased from 1.419 to 1.786, while the maximum Total Deformation increased from 0.12238 mm to 0.19347 mm. Although the deformation increased, its magnitude remains sufficiently small and does not affect the clamping function. Overall, the proposed V-Groove Block Clamp provides better stress distribution and a higher level of structural safety than the existing design, making it a feasible alternative clamping system for steel pole bending test machines.
