Abstract
The main commodity in the energy sector used in households is the availability of LPG packaged in pressurized steel tubes. To accommodate this, a continuous LPG cylinder production process is needed without significant impediment. It is not uncommon in the annealing process, production failure occurs due to damage to the shaft that holds the LPG cylinder. Under these conditions a change in shaft dimensions is required by theoretical calculations and solidwork software. The design shaft has material specification of medium carbon steel with dimensions of 0.9 m long, outer diameter of 76.1 mm, inner diameter of 70.3 mm. The shaft design is analyzed its structural strength and then compared with the strength of the previous shaft structure. This analysis produces data that the maximum stress received by the existing shaft is 278.59 MPa with a yield stress of 235 MPa. This means that the shaft experiences plastic deformation because the maximum stress exceeds the yield strength limit of the material. While the new shaft design has a maximum stress of 20.13 MPa with a yield stress of 235 MPa. This means that the shaft is not deformed because the maximum stress is far below the yield strength limit of the material. From the results of this analysis it can be concluded that the new design frame can be recommended to replace the existing shaft. Key Word: shaft, annealing, solidwork, Komoditas utama dalam bidang energi yang digunakan dalam rumah tangga adalah ketersediaan LPG yang dikemas dalam tabung baja bertekanan. Untuk mengakomodir hal tersebut, diperlukan proses produksi tabung LPG yang berkelanjutan tanpa adanya hambatan yang berarti. Pada proses Annealing, seringkali terjadi kegagalan produksi yang disebabkan oleh rusaknya shaft yang menahan Tabung LPG. Berdasarkan kondisi tersebut diperlukan perubahan dimensi shaft dengan menggunakan perhitungan secara teoritis dan software solidwork. Shaft perancangan memiliki spesifikasi material baja karbon sedang dengan dimensi panjang 0,9 m, diameter luar 76,1 mm, diameter dalam 70,3 mm. Rancangan shaft tersebut dilakukan analisis kekuatan strukturnya dan kemudian dibandingkan dengan kekuatan struktur shaft sebelumnya (existing). Analisis ini menghasilkan data bahwa tegangan maksimum yang diterima oleh shaft existing 278,59 MPa dengan tegangan luluh material 235 MPa. Artinya shaft mengalami deformasi plastis karena tegangan maksimum melebihi batas kekuatan luluh material tersebut. Sedangkan shaft hasil perancangan memiliki tegangan maksimum 20,13 MPa MPa dengan tegangan luluh material 235 MPa. Artinya shaft tidak mengalami deformasi karena tegangan maksimum jauh dibawah batas kekuatan luluh material. Dari hasil analisis tersebut dapat disimpulkan bahwa frame perancangan dapat direkomendasikan untuk menggantikan shaft existing. Kata kunci : shaft, annealing, solidwork
