Abstract

Proses pengangkatan (lifting) peralatan berat, seperti Diesel Particulate Filter (DPF), di lingkungan pertambangan menuntut keberadaan komponen lifting lug yang andal guna mencegah terjadinya kegagalan struktural. Penelitian ini bertujuan untuk menganalisis pengaruh variasi desain geometris lifting lug terhadap distribusi tegangan yang terjadi, membandingkan faktor keamanan (safety factor) dari masing-masing desain, serta menentukan konfigurasi desain yang paling optimal. Metode yang digunakan dalam penelitian ini adalah Finite Element Method (FEM) melalui simulasi berbasis perangkat lunak SolidWorks. Pemodelan dilakukan terhadap dua variasi desain, yaitu desain standar tanpa doubling plate dan desain rekomendasi dengan penambahan doubling plate. Pengujian dilakukan menggunakan material baja tahan karat AISI 316 dengan pembebanan statis sebesar 150 kg. Hasil simulasi menunjukkan bahwa desain tanpa doubling plate menghasilkan tegangan Von Mises maksimum sebesar 94 MPa dengan faktor keamanan sebesar 1,83. Sebaliknya, desain dengan penambahan doubling plate mampu menurunkan tegangan secara signifikan hingga 37 MPa serta meningkatkan faktor keamanan menjadi 4,65. Meskipun kedua desain tersebut sama-sama mampu menahan beban kerja yang diberikan, desain dengan doubling plate terbukti mendistribusikan tegangan secara lebih merata dan memberikan margin keamanan yang jauh lebih tinggi dibandingkan desain standar. Oleh karena itu, penambahan doubling plate direkomendasikan sebagai solusi desain yang paling optimal dan aman untuk diterapkan pada aplikasi pengangkatan beban di lingkungan industri berat.

The lifting process of heavy equipment components, such as the Diesel Particulate Filter (DPF), in mining environments requires a reliable lifting lug to prevent structural failure. This study aims to analyze the effect of geometric design variations of the lifting lug on the resulting stress distribution, compare the safety factor of each design, and determine the most optimal design configuration. The method employed in this research is the Finite Element Method (FEM) through simulation using SolidWorks software. Modeling was conducted on two design variations, namely a standard design without a doubling plate and a recommended design with the addition of a doubling plate. Testing was carried out using AISI 316 stainless steel material under a static load of 150 kg. The simulation results show that the design without a doubling plate produced a maximum Von Mises stress of 94 MPa with a safety factor of 1.83. In contrast, the design incorporating a doubling plate was able to significantly reduce the stress to 37 MPa and increase the safety factor to 4.65. Although both designs were capable of withstanding the applied working load, the design with the doubling plate was proven to distribute stress more evenly and provide a substantially higher safety margin compared to the standard design. Therefore, the addition of a doubling plate is recommended as the most optimal and safe design solution for lifting applications in heavy industry.
