Abstract
Corrugated metal gaskets (CMG) made from SUS304 have previously been developed, however a coating process with a softer material is necessary for its design to be optimal. The coating process is time consuming and expensive. This research aims to develop CMG from aluminum by simulation analysis and form a CMG design made of aluminum A1100. The method used is development research. The optimum CMG thickness is analyzed using ANSYS Finite Element Analysis (FEA). The control variables being investigated are contact area and contact stress. The independent variable being investigated is the material thickness of CMG. An aluminum gasket is then constructed using a cold-forming process based on the optimum design. The control variables in the leak test are axial force and water pressure. Experiments were also carried out to test the aluminum gasket for leakage. A leakage test is carried out using a water pressure test. Simulation analysis showed results that were in line with experimental leak tests. FEA simulation results show that the optimum gasket thickness is between 3 and 5 mm, with 5 mm being the most optimal. However, CMG with thicknesses of 4 and 5 have similar contact stress and contact area. Leakage test results also show similarities with simulation results. CMG with a thickness of 5 mm has the best performance. The experimental results show that CMG made from aluminum A1100 is suitable for use as a gasket to prevent leakage, it prevents leakage at fluid pressure up to 12 MPa and axial force 100 kN. The results show that aluminum CMG performs on par with SUS304 CMG coated with nickel or copper. This research succeeded in developing CMG made of aluminum
