Abstract
This study aims are to analyze stress and displacement using Finite Element Method (FEM) of the three components design of powder packaging machine. The safety factor (SF) is calculated to compare with the design acceptance criteria, more than two. The frame is made of ASTM A36 steel angle bar, while the camshaft and sealer sleeve of AISI 1018. Steel angle bar widths of 40x40 (mm) and 50x50 (mm) with a thickness of 3,4,5 (mm) use for the frame design variant. The diameters of the camshaft design variants are 0.75”, 1”, and 1.25”. Then, the sealer sleeve variant utilizes thicknesses of 10, 12, and 14 (mm). Loading assumption during adverse operating conditions, such as when there is an obstacle or jam. Through the finite element method results, increasing the thickness of the frame also the sealer sleeve, and increasing the diameter of the camshaft, produced a decrease in the value of von mises stress and displacement. The safety factor for all variants of frame thickness was more than two, indicating that all designs were safe and acceptable. Nevertheless, there is one design failure on the camshaft and sealer sleeve because the SF value is less than two.
